/**
* XPaths in FontoXPath know of two separate contexts: the static one and the context at evaluation.
*
* Because FontoXPath allows injecting variables and namespace declarations at evaluation time, static compilation _may_ depend on evaluation context.
*
* If it does, this execution context will be used to mark the statically compiled selector as
* specific for the evaluation context. If the XPath did not depend on the evaluation context, it
* will be reused.
