This is why there is an API and a language
specification. The parser is written and maintained
once (currently in Java but hopefully once an ANTLR
version hits .NET it will be ported and thus support
multiple languages) while conformant implementations
simply implement the underlying API and get not only a
decent API for interacting with the XML repository but
get SiXDML support for free.
