In the following document

  RDFa Core 1.1 - Second Edition
  http://www.w3.org/TR/2013/REC-rdfa-core-20130822/

there is a false claim. In appendix A http://www.w3.org/TR/2013/REC-rdfa-core-20130822/#s_datatypes it says:

  'Markup languages that want to import these definitions can find them in the "datatypes" file for their schema grammar:

	 DTD xhtml-datatypes.mod
	 XML Schema xhtml-datatypes.xsd'

Now I am not a markup language, but I don't think anyone, not even a markup language, can find, today, a definition for CURIEorIRI in the referenced .xsd file i.e. http://www.w3.org/MarkUp/SCHEMA/xhtml-datatypes-1.xsd . (I did not check the DTD but I suspect it is also involved.)

It appears to me to be a deployment omission for this spec. The missing properties are those that were added between 1.0 and 1.1. This should be corrected by W3C staff by editing the .xsd file.

I recommend also adding to the .xsd file a reference to the RDFa Core 1.1 in the form of a URI for the spec or the appendix. The URI could go in an xs:documentation element or in  a comment (per your judgment) but I think xs:documentation is probably better since it would then be machine linkable.

This kind of problem has happened in the past with at least one other spec, so I also recommend adding a step to the publication process to check that claims made about referenced documents are actually true (at least at the time of publication) and that FYN works for all URIs.
