See: (http://www.w3.org/XML/Group/2003/05/xml-schema-ftf-minutes#d0e750 XML Schema Part 2 suggests that the XMLSchema-datatypes URI is an alias for the xmlschema namespace URI: "To facilitate usage in specifications other than the XML Schema definition language, such as those that do not want to know anything about aspects of the XML Schema definition language other than the datatypes, each built-in datatype is also defined in the namespace whose URI is: http://www.w3.org/2001/XMLSchema- datatypes " while the documentation in the schema for the XMLSchema-datatypes suggests a different relationship, which is consistent with the notion of one-name-per- component: <documentation>Note this schema is NOT a normative schema - - It contains types derived from all the builtin simple type definitions with the same local name but in a distinct namespace, for use by applications which do no wish to import the full XMLSchema schema. Since derivation is not symmetric, unexpected results may follow from mixing references to these definitions with references to the definitions in the XMLSchema namespace. For example, although dt:positiveInteger is derived from xs:integer, the converse does not hold.<documentation> See bug 2214 for resolution of this issue in schema 1.1.
