the infoset simply distinguishes 'attributes' and 'namespace
attributes', but both kinds of attributes are modeled as attribute
information items, the latter being checked for conforming to the
validity constraints of xml namespaces.

what i wanted to say was that *hypothetically* it would be possible to
define a non-namespace infoset, and then to specify how to derive an
namespace-infoset from it. i was not clear enough in saying that this
process would also involve moving of namespace declaring attributes from
an element's 'attributes' property to its 'namespace attributes'
property, but the process i had in mind remains the same.
it was simply an attempt to show people that things like what i am
proposing are already going on, even though they are hidden because the
infoset currently is monolithic.

ha! and now it's my turn! you are wrong! i am right! ;-) namespace
declarations actually can be reached via *two* paths, one being the
'namespace attributes' property, the other one being the 'in-scope
namespaces' property. via the first way, you get them as attribute items
(in their markup flavor), via the second way, as namespace items (in
their namespace flavor).
to summarize: namespace-awareness changes attributes declaring
namespaces by moving them from the general 'attributes' to the special
'namespace attributes' property, and by deriving namespace items from
them (and making these namespace items accessible from element items).
