ISSUE-146: HTML5+RDFa needs rule for implied @about="" on head/body

HTML5 head/body

HTML5+RDFa needs rule for implied @about="" on head/body

State:
CLOSED
Product:
RDFa 1.1 in HTML5
Raised by:
Gregg Kellogg
Opened on:
2012-12-26
Description:
XHTML+RDFa has the following clauses for Step 5 and Step 6 to act as if there is an implied @about="" on head and body elements:

In section 7.5, processing step 5, if no IRI is provided by a resource attribute (e.g., @about, @href, @resource, or @src), then first check to see if the element is the head or body element. If it is, then act as if the new subject is set to the parent object.
In section 7.5, processing step 6, if no IRI is provided by a resource attribute (e.g., @about, @href, @resource, or @src), then first check to see if the element is the head or body element. If it is, then act as if the new subject is set to the parent object.

These rules are missing from HTML5+RDFa; I presume that these are intended there as well, but were left out due to an oversight. Test 0066 tests for this, and would fail for HTML5/XHTML5 otherwise.

Related notes:

Gregg updated the latest spec to add this language. Specifically, this text:

In Section 7.5, processing step 5, if no IRI is provided by a resource attribute (e.g., @about, @href, @resource, or @src), then first check to see if the element is the head or body element. If it is, then act as if the new subject is set to the parent object.
In Section 7.5, processing step 6, if no IRI is provided by a resource attribute (e.g., @about, @href, @resource, or @src), then first check to see if the element is the head or body element. If it is, then act as if the new subject is set to the parent object.

However, I thought that we added the following to the RDFa Core specification in order to remove language like the above:

"otherwise, if the element is the root element of the document, then act as if there is an empty @about present, and process it according to the rule for @about, above;"

We published the XHTML1+RDFa 1.1 spec with the language above in it and I don't know if we intended to do that. If we didn't intend for that to happen, we might want to do a PER for XHTML1+RDFa 1.1.

So, we either add the language above to HTML+RDFa 1.1, or we remove the language from both HTML+RDFa 1.1 and XHTML1+RDFa 1.1.

Looks like we resolved to not do this for both HTML+RDFa and XHTML+RDFa:

RESOLVED: Add text matching XHTML+RDFa 1.1 for special processing of HEAD and BODY into the HTML+RDFa 1.1 spec.
