Re: ISSUE-97 (HTML5 datetime support): Determine if datetime should be supported in HTML5 [RDFa 1.1 in HTML5]

What I presume you mean is that the datetime attribute is an implicit short hand for 

content="@datatime value" datatype="xsd:dateTime"

and @data attribute is implicit short hand for @resource

with the understanding that if there _is_ a @content, resp. @resource attribute set by the user, that has a priority.

I am perfectly o.k. with this. It is, conceptually, a shorthand for HTML5 and does not distort anything on the processing level.

These tags are <time> and <object> where the property value comes from @datetime and @data, respectively. It is to be expected that HTML5 authors will place relevant values in these attributes, and I'm wondering how RDFa 1.1 can target these without resorting to adding a content attribute.
