    module.exports = (File) ->
        {AttrChange} = File

        (file) ->
            {attrChanges} = file

            nodes = file.node.queryAll "neft:attr"

            for node in nodes
                target = node.parent
                name = node.attrs.name

                unless target.attrs.has(name)
                    target.attrs.set name, ''

                attrChanges.push new AttrChange file, node, target, name
