I have talked to Mike Smith, here is what he said. Usage of @xmlns:XXX is not called out explicitly as an error in HTML5. But it is an error due to the fact that HTML5 does not treat @xmlns:XXX specially; it is an attribute that is not defined for HTML5. As a consequence, using @xmlns:XXX is an error just as using @foo is an error because @foo has not beed defined neither as a global attribute nor as a local attribute for any particular element. > > That is good enough for me to resolve ISSUE-126 as accepting @xmlns:XXX as an error in HTML5+RDFa (actually, not only for a validator, but in general). +1 @prefix is the right way to define prefixes anyway. @xmlns is a vestige that isn't required for HTML5.
