But I think that the RDFa Core spec should also be compatible with hypothetical/future/unknown host languages.  I could very well imagine potential host languages that already exist, or future host languages in whose initial design RDFa is not taken into account, which already have one of the RDFa attributes, but with a different meaning.

Thus, wouldn't it make sense to introduce an optional RDFa namespace?  Then, any host language should be able to say e.g.

<element rdfa:about="http://..." about="life, universe, everything"/>
                                 ^^^^^

                                 suppose this is the native @about attribute of
                                 the language, which has a different semantics
                                 than RDFa's @about
