The very point is that a namespace should *not* direct behavior
in and of itself. The 1:1 correspondence between namespace
and vocabulary or namespace and doctype or namespace and
some web resource is not a part of the Web architecture. It
may be a common misconception about the Web architecture,
but it is not thus defined.

Software may not expect to rely on any such 1:1 correspondences.

If they do, and it works, fine, but it remains a hack, and
good system engineering is not based on hacks.

Right?

Cheers,

Patrick
