Hello, RDFa folks.

Per the current RDFa spec, the following code

<link rel="alternate stylesheet" href="alt.css"/>

forms two triples:

<> xhv:alternate <alt.css> .
<> xhv:stylesheet <alt.css> .

However, the subject represents a HTML document, which cannot be
alternated by a CSS stylesheet. So rel="alternate stylesheet"  need a
special care, otherwise all the documents with these values specified
generate improper triples.

I suggest adding some rules for handling this case, either by 1)
dropping the "alternate" clause, or 2) introducing a new
"alternate-stylesheet" property (or something like), or 3) dropping
these triples altogether.
