This section is normative for purposes of defining the integration of the XHTML Metainformation Attributes Module into XHTML 2. The semantics of the XHTML Metainformation Attributes Module itself are normatively defined in [RDFASYNTAX]. The rules for extracting RDF from XHTML family markup languages are defined in [RDFASYNTAX]. For information on important differences between XHTML 2 and other XHTML family markup languages and how those may relate to RDFa, see Appendix A.
