You are right, the 'official' URI is without the .html, which then is dereferenced using content negotiation. The context in the text is, however, for authors to see the predefined prefixes, for which the .html is also fine.

In any case... the current draft referred to the old, /ns/profile URI, which is definitely wrong!

Thanks

Or can I use mailto:ivan@w3.org as a property value in microdata (not that I would like to, but you take the point...)? I know that there is a separate section on some of the issues later, but the reader, getting to that point, might be confused...

I realize that this is the nature of the beast, because mixing vocabularies in microdata is simply complicated, but it really breaks the flow of the reading that the relevant rdfa and microformat sections are both 1-2 paragraphs, whereas the microdata one goes on for pages. If a potential author reads this for the first time, it is easy to be lost.

I would expect, at some points, processors coming up that would 'distill' both RDFa and microdata from a document and merge that in RDF; I am sure Gregg will do that, and I may do the same at some point when the microdata->RDF mapping gels...
