I was partly confused by the titles of the documents, but looking in more detail, "XHTML+RDFa 1.1" is for mixing in RDFa 1.1 to XHTML 1.1 whereas "HTML+RDFa 1.1" is about RDFa 1.1 support in HTML4, HTML5 *and* XHTML5. So there are almost bound to be differences between the two specs.

It's relevant for the link relations issue: it might be fine to use the IANA link relations for XHTML 1.1 + RDFa 1.1 but it doesn't really work with (X)HTML5 + RDFa 1.1. (I wonder whether it works with HTML4)
