Adds a datatypeLibrary-aware datatype resolver to the XML-syntax parser: the in-scope library is inherited from the nearest ancestor, the default (empty) library defines only string and token, and the W3C XML Schema library defines the full built-in set. A type the in-scope library does not define is an unknown datatype, so the <data>/<value> pattern matches nothing rather than silently validating. Adds an nsNameExcept name-class case so nsName with an <except> child (XML syntax) and prefix:* - name subtraction (compact syntax) narrow a namespace wildcard. The compact lexer splits prefix:* into a trailing- colon word plus a star symbol, which the parser now recognizes. Existing RELAX NG facet tests declared XSD types without the library and relied on lenient resolution; they now declare the XSD datatypeLibrary, matching what a conformant processor requires.
