This PR primarily affects the grammar file, simplifying it to remove most of the material that is only there to support the generation of a JavaCC parser (which has probably not been achievable since XPath/XQuery 2.0).
The section of the grammar that defines the binary operators starting with
OrExpris now expressed using conventional production rules, rather than the precedence-based grammar previously used. This allows deletion of some convoluted code in grammar2spec.xsl.The DTD for the grammar file is revised to exclude many constructs that are no longer used.
Many simple token definitions (especially those that consist of a simple constant string) have been inlined.
