 59. added @NISO attribute to designate which        2015-01-15  (cmg)
      sections to be included in Standards documents                

 58. Converted to Taglib 8
                                                     cmg 2014-01-8

 57. TWEAKS TO SUPPORT 'COLLECTIVE' DEVELOPMENT
 
                                                     wap 2011-03-16
                                                     
     Added optional id (type ID) to elem.sec and attr.sec

                                                     wap 2011-03-15
     Added linebrk to %paracon;, allowing it in tables (by way
     of %Flow.mix;)
     
                                                     wap 2010-06-15
 
     Parameterized models for elem.info.content, attr.info.content
     and pe.info.content, allowing them to be overridden by a
     calling DTD.

     Loosened models of pe.sec and dtd.sec so all contents are
     optional (except dtd.sec/title); this is more flexible and
     conforms to elem.sec and attr.sec.
     
 56. TWEAKS ADDRESSING USER REQUESTS                 wap 2010-06-11
 
     Added codeblock to related.elem and to attr.usage
     
 55. GENERAL RATIONALIZATION                         wap 2010-06-11

     As part of the general fixing and cleaning of filenames
     and references, renamed Taglib7.dtd.
     
     New FPI is
     
     "-//Mulberry//DTD Mulberry Technologies Tag Library 7 XML 20100611//EN"

     Restored #FIXED attribute value for xmlns:mtl
     at the top level ('http://www.mulberrytech.com/taglib')
     
 54. Added newer ToC support elements:
       insert.ContextTable
       insert.Index
       insert.TagElementIndex
       insert.ElementTagIndex
     These act as placeholders for the merge routines, which then
     replace them with the appropriate structures.   wap 2008-09-22

 53. Added new toc.listing element to the top level. (We decided
     to wait before adding it to intro, chapter and section.)
                                                     wap 2008-09-18

 52. Altered top-level content model from

     mtl:taglibdefs (metadata, intro?, chapter*, elem.sec?,
                     attr.sec?, pe.sec?, context.info?, chapter*,
                     dtd.sec?, index.sec?)
     to
                    (metadata, (intro | chapter | elem.sec |
                     attr.sec | pe.sec | context.info | dtd.sec |
                     index.sec)*

     Reasons: the old model is non-deterministic; also we want
     to be able to add top-level elements to the model (see 53).
                                                     wap 2008-09-18

 51. Change 'content.model?' to 'content.model*' in 'pe.info' to
     reflect current usage of both unexpanded and expanded content
     models for PEs in some tag libraries.           tkg 2008-06-10

 50. Added 'chapter*' before 'elem.sec' in mtl:taglibdefs.
                                                     tkg 2008-04-14

 49. Removed <examp.desc> since  unused.  Added <index.sec>.  Added
     'index' attributes.  Renamed <synonym> to <index>.
                                                     tkg 2008-01-28

 48. Added <format.examp> and <tagged.examp> to %para.level;.
     Made <title> optional in <intro>.               tkg 2007-09-24

 47. Removed <focus> since comment 33, below, deprecates <focus>.
     Added <mtl:mksafe> as replacement for mksafe PIs.  Added
     <title> on <intro>.                             tkg 2007-09-18

 46. Changed PUBLIC identifiers of Taglib DTD components to SYSTEM,
     as this DTD needs to be entirely self-contained (so that
     catalogs can be relied on freely for DTDs it processes without
     fear of interference).                          wap 2007-09-04

 45. Renamed 'expandPEs' attribute to 'expandedOrUnexpanded'.
                                                     tkg 2007-08-31

 44. Added 'synonym' to element, attribute, and PE definitions and
     to chapter.  Added pe.tag.ref to content.model content model.
     Added 'expandPEs' attribute to content.model for when content
     models extracted from schema as part of processing.  Added
     examp.group to group related formatted and tagged examples.
     Allowed sections inside remarks.                tkg 2007-08-17

 43. Added 'sortAs' attributes so sorting can be independent of
     how any particular downstream processor feels about sorting
     '.', '-', and ':'.                              tkg 2007-05-30

 42. Added code and quoted as inline elements, per user requests
                                                     wap 2006-06-09

                                                      kh 2006-03-27
 41. Added a "scale" attribute to accompany the "picfile"
     attribute on its three elements: graphic, inline.graphic,
     and tagged,examp.
     The need to scale a graphic arises from print production.
     The scale attribute is NOT CURRENTLY USED (2006-03-27) in
     HTML production.
     It was decided not to rev the DTD, which remains at v0.15.


      CHANGES                   (BTU)                v0.15 20040707

 40.  Added suggested.values to model for elem.value.group inside
      attribute descriptions: allows separation of remarks on an
      attribute from remarks on suggested values for them
      (especially on CDATA attributes).

      CHANGES                   (BTU)                v0.14 20030323

 39.  Added <linebreak> to model of sponsor.

      CHANGES                   (WAP)                v0.14 20030225

 38.  Added optional id attribute to <intro> so it can be targetted
      by a cross-reference directly (without using a <target>).

 37.  Changed <section> to <chapter> at the top level (inside
      mtl:taglibdefs); restored a declaration for <chapter> ...
      their semantics are different (chapters must break out
      new HTML pages, sections will be controllable).

 36.  Added 'keep' attribute to <section> so user may control
      whether it will generate a file (the default) or be kept
      with its parent (keep='yes')

 35.  Changed ext.ref attribute on ext.cross.ref to make #REQUIRED

      CHANGES                   (KAH)                v0.13 20021004

 34.  Added codeblock to remarks.

 33.  Changed focus to mtl:focus throughout. Now that we're
      validating tagged samples, this is necessary!

      And, temporarily, allowed both focus and mtl:focus,
      because the display process is (a) producing focus,
      and (b) not displaying mtl:focus correctly.

      Fix for that is: find the places that still use focus,
      and reform them to use mtl:focus. Then remove all mention
      of focus.

 32.  Changes to ensure and reveal that taglib processing is picking
      up the taglib DTD and entity sets from the TaglibDTD directory,
      and that no client DTD is picking up these entity sets or
      liable to do so:

      a) Changed DTD PUBLIC and SYSTEM identifiers

      from TagLibDefsV0.13.DTD
        to TLDv0-13.dtd

      from
         -//Mulberry//DTD Mulberry Technologies Tag Library 2 Definition DTD v1.0 20010909//EN//XML
        to
         -//Mulberry//DTD Mulberry Technologies Tag Library 2 v0.13 XML 20010909//EN

      b) Changed ISO charset pe names and PUBLIC and SYSTEM identifiers,
         by adding "TLD" on the following model:

      pe name     TLD-isolat1
      SYSTEM ID   TLD-isolat1.pen
      PUBLIC ID   ISO 8879-1986//ENTITIES Added Latin 1 for TLD//EN

      Changed Mulberry entity.map accordingly.
      Changed taglib script "mkskel11.xsl" accordingly.

      Added "euro" declaration so we can keep this at v13.


      CHANGES FOR REVISION 0.13 (PMR)                v0.13 20020601

 31.  Added <codeblock> element for general use and specifically
      for tagged examples that are not children of <elem.info>

 30.  Added attribute 'autolink' to elem.name.ref, elem.tag.ref,
      attr.name.ref, attr.tag.ref, pe.name.ref, and pe.tag.ref
      with possible values of (yes | no), with yes the default.
      Used to suppress generation of a link in html output when
      autolink="no"

      CHANGES FOR REVISION 0.12 (PMR)                v0.12 20020521

 29.  Added attribute 'type' to element 'emphasis', with possible
      values of (mono | ital | bold), with ital the default.

      CHANGES FOR REVISION 0.11 (TRG)                v0.11 20020516

 28.  Added declarations/invocations for the XML version of ISO
      character entity sets:  %isolat1; %isonum; %isopub; %isotech;

 27.  Deleted specific character entity invocations for &amp;,
      &percnt;, &lt;, &gt;, &rdquo;, and &ldquo;

      CHANGES FOR REVISION 0.10 (PMR)                v0.10 20020411

 26.  added new elements to metadata: shortname, headname, type
      to help in process control.
        shortname is used in generating filenames
        headname is used to generate running heads and such
        type tells us whether this is an xml or sgml dtd
      added root-element as an attr to context.info to help in
        generating the context table. (PMR)
      linebrk added as allowed element in developer
      working.notes removed because replaced by note.to.reviewer.


      CHANGES FOR REVISION 0.92 (PMR)                v0.92 20020320

 25.  changed all three picfile attributes from ENTITY to CDATA
      because of inability of XSLT to copy an internal subset when
      doing a transform. Therefore, the indirection mechanism for
      pointing to files fails unless you manually copy the internal
      subset back in after each transform.  Rather than do this, we
      will hard code the file locations in the picfile attr.
      As a consequence, dropped entities added in change 22.  (PMR)


      CHANGES FOR REVISION 0.91 (PMR)                v0.91 20020219

 24.  made behavior optional in value.cluster (PMR)

 23.  added basic metadata elements (PMR)

 22.  added external entities for the near and far key (PMR)

      CHANGES FOR REVISION 0.9 (PMR)                  v0.9 20020204

 21.  paracon entity removed from the the dtd because it was needed
      only for the OPEN/CALS table model, which is no longer
      being used. (PMR)

 20.  sgml.model removed from the two content models that use it
      because it is not defined as an element. Comments have
      been left indicating where it was used.(PMR)

      CHANGES FOR REVISION 0.8 (PMR)                 v0.8 20020122

 19.  #PCDATA removed from paracon entity declaration to avoid
      conflict with html table model - paracon is not used anywhere
      else in this dtd (PMR)

 18.  NOTE: sgml.model is referenced in content models for dtd.info
      and figure, but is never defined as an element (PMR)

 17.  commented out unused internal pe 'schemaAttrs' and
      'attributeAttrs' (PMR)

 16.  replaced SGML OPEN/CALS EXCHANGE table module with XHTML
      table module (PMR)

 15.  removed attr 'elem.refs' from element attr.info because
      elem names stored there were repeated in elem.name.ref+ (PMR)

 14.  changed 'SGML.model' to 'sgml.model' in content model for
      element 'figure' to correct case problem (PMR)

 13.  completed change (10) by moving attr.value.group to a more
      logical place (after elem.name.group), and changed comment
      on elem.value.group to be clearer. (PMR)

 12.  changed the name of 'id' attr (of type ID) on pe.info to
      'name' to be consistent with usage on elements elem.info
      and attr.info (PMR)

 11.  added content.model to the content model for pe.info (PMR)

      CHANGES FOR REVISION 0.7 (PMR)                 v0.7 20020111

 10.  Changed <attr.value.info> content model to remove
      <attr.value.group> (leaving only <elem.value.group>)
      so that every <attr.value.group> will be contained by an
      <elem.value.group>. (PMR)

      CHANGES FOR REVISION 0.6 (BTU)                 v0.6 20011227

  9.  Added <intro> to taglib model. It was already available inside
      named sections, but not for whole tag library. (BTU)

  8.  Added <section> as generic titled structure. Specifically to
      hold Near & Far diagrams, but also for other uses if needed.
      (BTU)

  7.  Added DTD section <dtd.sec> (BTU)

  6.  Removed element to tag and tag to element index elements
      because these indexes can be generated on display and don't
      belong in the edited file. (BTU)

      CHANGES FOR REVISION 0.5 (BTU)                 v0.5 20011220

  5.  Reversed change 3, below. attr.value.group model back to:
      (value.cluster+, default.value?)
      because it makes no sense to have a default if there is no
      value (BTU)

  4.  Add examp.desc to tagged.examp (BTU)

      CHANGES FOR REVISION 0.4 (BTU)                 v0.4 20011017
      CHANGES FOR REVISION 0.4 (PMR)                 v0.4 20011017

  3.  Allowed value.cluster to occur * rather than ? (PMR)

  2.  Added model for model.desc (BTU)

  1.  Added model.desc to elem.info (BTU)

                                                                   -->
