datatypes — Namespace declaration (to identify datatype libraries)
"datatypes" identifierOrKeyword "=" literal |
The datatypes declaration assigns a prefix to a datatype library for the compact syntax, like xmlns:xxx attributes in XML. Note that unlike XML namespace declarations, declarations for the RELAX NG compact syntax in general (and datatypes declarations in particular) are global to a schema and can't be redefined. The prefix xsd is predefined and bound to http://www.w3.org/2001/XMLSchema-datatypes.
