Document Conformance
Conformance to Syntax
An RDFa document is any XHTML 1.1 document.
Conformance to Semantic
A XHTML 1.1 document is said to carry an RDF graph, which can be extracted by means of applying the extracting rules defined in the RDFa Syntax document.
Extractor Conformance
An RDFa extractor takes an XHTML 1.1 document and generates an RDF graph by applying the RDFa extraction rules. Note: The resulting RDF graph is not expected to include all possible features of the RDF Recommendation, e.g. reification and containers are not supported.
