… indeed you had said that before.  As you say "annoying", am I right to assume that OpenDocument could afford putting the RDFa attributes into the empty namespace?  I.e. that there are no conflicts with other attributes having the same name.

Shane has fixed that to "either empty namespace or XHTML namespace" for now, which should IMHO cover all cases.  Therefore I consider my suggestion of obsolete.

I completely agree.  (Maybe that should be made explicit in the spec.)  Otherwise it would inevitably lead to confusion, particularly in cases such as

<element about="..." xhtml:about="..."/>
