ISSUE-147 (preserve markup by default): RDFa Processors should preserve markup by default [RDFa 1.1 in HTML5]

http://www.w3.org/2010/02/rdfa/track/issues/147

Raised by: Manu Sporny
On product: RDFa 1.1 in HTML5

This issue was raised by Sebastian Heath:

HTML5 and its variants such as XHTML5 provide a rich set of elements that content creators use to indicate many aspects of the texts they are representing. When processing RDF in attributes, the "RDFa 1.1 in HTML5" specification [1] should by default require preservation of all intentional markup. This is good practice. In particular, the working group should not assume that elements in content marked with the @property attribute are there by mistake. Nor should the replication of namespaces in the output be considered garbage.

Full reasoning is here:

This issue is being re-opened because of the following statements:

"This is good practice. In particular, the working group should not assume that elements in content marked with the @property attribute are there by mistake. Nor should the replication of namespaces in the output be considered garbage."

The working group should re-examine if:

1) Preservation of markup is good practice for RDFa Processors.
2) The inclusion of HTML markup by authors was not a mistake and the feature is causing problems in RDFa 1.1 based on 6+ months of deployment experience.
3) The replication of namespaces should be considered garbage (I don't think the WG ever said this, and the assertion is most likely due to a mis-communication at some point).
4) Changing the rules at this point would cause an undue burden on authors and implementers due to conflicting rules between RDFa Core and HTML+RDFa.
