ISSUE-126: Can use of xmlns: be reported as an error for HTML5+RDFa 1.1?

HTML5+RDFa conformance

Can use of xmlns: be reported as an error for HTML5+RDFa 1.1?

State:
CLOSED
Product:
RDFa 1.1 in HTML5
Raised by:
Manu Sporny
Opened on:
2012-01-19
Description:
This issue was raised by Michael(tm) Smith:

He was working on the new validator code for W3C and said that getting xmlns: support into the HTML5 validator was going to be a fairly large undertaking. Additionally, we're the only ones that override the HTML5 spec to add xmlns: support, even though we have deprecated its usage.

Additionally, Mike mentioned that the underlying SAX implementation doesn't even expose xmlns: declarations to the validator, which would require a fairly in-depth reworking of the internals of the SAX processor that they're using. In other words, implementing this isn't as straightforward as it may have seemed when the specification was written.

Mike would like to see the following text:

"Conformance checkers must accept attribute names that have a case insensitive prefix matching "xmlns:" as conforming. Conformance checkers should generate warnings noting that the use of xmlns: is deprecated."

to this (for HTML5+RDFa):

"Conformance checkers may report the use of xmlns: as an error."

RESOLVED: Change the conformance checker section to read "Conformance checkers MAY report the use of xmlns: as an error".
