Description Maciej Stachowiak 2010-02-14 07:17:37 UTC 
"While it is specified that HTML5 must preserve these attributes in the DOM, it must also accept these attributes as conforming in non-XML HTML5."

This appears to place a requirement on the HTML5 spec itself. HTML5 does not accept these as conforming, nor does it seem appropriate to state that it "must". Instead it should be stated that under this specification, they are conforming for documents and conformance checkers must treat them as such.

Status: Fixed

Change Description: 

Moved requirement from HTML5 spec, to HTML5 documents and conformance checkers:

"""
Since RDFa uses attributes starting with xmlns: to specify CURIE prefixes, any attribute starting with a case-insensitive match on the text string "xmlns:" must be preserved in the DOM or other tree-like model that is passed to the RDFa Processor. For documents conforming to this specification, attributes with names that have a case insensitive prefix matching "xmlns:" must be considered conforming. Conformance checkers must accept attribute names that have a case insensitive prefix matching "xmlns:" as conforming.
"""

Rationale:

Conformance requirements should be on the document and on conformance checkers, not the HTML5 spec.
