itemprop may take an 'absolute URL'. However, an 'absolute URL' is defined in terms of resolving onto itself and the algorithm for resolving URIfies URLs. Therefore, it seems that an absolute IRI cannot be an absolute URL. Since RDF seems to allow IRIs as properties and the current practice is to allow IRIs in various places, it seems to me that itemprop should take absolute IRIs instead of absolute URLs or the definition of absolute URL should be adjusted.
I wrote the above on public-html. Hixie advised me to bring it to your attention specifically, because it seems the definition of 'absolute URL' has undesirable implications. That is, a definition under which an absolute IRI is also an absolute URL would be desirable.
