Comment on RDFa Primer concerning attributes @resource, @content and @datatype

Hi!

I have read the latest primer as of 2008-06-20, and I have one comment. I would like to see examples for the use of the attributes:

  @resource
  @content
  @datatype

Maybe this can be put in an "Advanced stuff" section near the end of the document. HTML people might get a bit confused by this discussion, but I think that for RDF people it is very important to know how one can embed data into HTML, for which there is no clickable link (href attribute) or text within an element. 

There are such examples in the RDFa Reference, but most people will probably only read the Primer, and RDF people shouldn't get the impression that something very important had been forgotten.

Regards,
Michael
