Possible RDFa errata - 4.1 Document Conformance

4.1 Document Conformance
http://www.w3.org/TR/rdfa-syntax/#docconf

| A strictly conforming XHTML+RDFa document is a document that requires
| only the facilities described as mandatory in this specification. Such
| a document satisfies the following criteria:
|
| 1. The document MUST conform to the constraints expressed in the
| schemas in Appendix A - XHTML+RDFa Document Type Definition.

However, the DTD given doesn't allow for xmlns:* attributes which are
beyond the ability of DTDs to deal with.

I propose one of two solutions:

1. Preferred - change the conformance requirement to: "With the
exception of xmlns:* attributes, the document MUST conform to the
constraints expressed in the schemas in Appendix A - XHTML+RDFa Document
Type Definition." The W3C XHTML validator already does this when
checking document conformance.

2. Less preferred - drop this criterion and make Appendix A informative.
