Hi Henri,

Same goes for any attribute name beginning with four z's, or
containing the sequence 'banana'; none of them are required by any
particular spec, yet removing them would be somewhat cavalier.

But I note that you say "in non-browser apps"; are you saying that
attributes beginning "xmlns:" would be preserved in an HTML5 browser?

Yes, you've said that. :)

Ah...the bogus word again. You certainly have a rapier-like debating
style, Henri...no mistake.

Of course, whether something is bogus or not is exactly what debates
are supposed to prove, so throwing the word around adds nothing. You
certainly haven't proved that it is 'bogus' to make the following
claim; that implementing an RDFa parser in JavaScript, on top of an
HTML or XHTML DOM -- such as in a browser -- is not at all
problematic.

Regards,

Mark
