Is GRDDL supposed to work with text/html? The GRDDL spec seems to focus on XHTML. If it's for XHTML only, then it doesn't matter what text/html registration says.

Do GRDDL processors actually rely on profile attribute? 
When researching pages with microformats (on 'anecdotal' scale) I found that that few of them used profile at all, and some of them had irrelevant/invalid profile, e.g. XFN profile on page with hCard. In case of microformats I think that tool which respected profiles would be worse off than tool that ignores profiles completely (I don't know if that's true for GRDDL in general).

Are there conflicting vocabularies used in the wild that couldn't be processed correctly without disambiguation with profile? Couldn't <link rel=transformation> be used instead?
