yes; agreement on all points.
mr. harold is not the only one who would have benefitted.

the only aspect of which i can comprehend, is the claim, that, being able to
bind the prefixes over a dtd would have broken the rule that namespaces should
not "change the validity of a given document". which claim is true, but which
i believe to be fundamentally misdirected.

it's an old argument.
