These parsers are kept up to date with the latest drafts of XPath 2.0 
and XQuery 1.0, and the text description in the specifications is 
generated from the same grammar as the parser, all the examples in the 
specifications (including the use cases) are tested with them, and they 
have had wide review. So there are real advantages to using them. Unless 
you need an XPath 1.0 parser.
