After finding the current recs, I think I understood but don't like it.

My usecase is an application (KnoBot [1]) delivering rdf on http 
requests, it honours the accept-language header on a per literal basis, 
literals in a language that is not in the accept-language header are not 
ignored, the others are sorted according to the user preferences. Now I 
don't like the idea to xml-parse every literal.

Then I would have assumed a semantic difference between the language of 
the literal, and the language of the elements in the xhtml.

<ex:Book>
    <dc:title xml:lang="de">Carpe diem</dc:title>
</ex:Book>

I would have thought that this means that the title of the German 
(translation of a) book is "Carpe diem". Similarly to quotes in foreign 
language within a document, if xml:lang would be legal with XMLLiterals 
I would have understood the following to express that "Carpe diem" are 
Latin words expressing the German title of the book.

<ex:Book>
    <dc:title xml:lang="de" rdf:parseType="Literal"><span
xml:lang="la">Carpe diem</span></dc:title>
</ex:Book>
