Okay, first cut of implementing @profile goes into an infinite loop. Section 7.5 item 3 indicates that any element containing an @profile document is processed as indicated in RDFa Profiles (section 9). Test 0089 contains <head profile="http://www.w3.org/1999/xhtml/vocab">, which causes the parser to load <http://www.w3.org/1999/xhtml/vocab> to extract the vocabulary. That vocabulary also contains the same <head> element, so the parser goes into an infinite loop. Clearly, the parser can check for a recursive call to call an already opened profile, but the processing instructions should discuss this. It seems that in the case of < http://www.w3.org/1999/xhtml/vocab>, it is intended to note that this defines a profile, not requires a profile. Should processing rules be different the <head>, is the profile use in this case just wrong? In any case, it looks like an existing useage pattern that is incompatible with the processing instructions. Gregg
