2.2 Element Information Items

- [in-scope namespaces].a

does not the absence of items corresponding to the prefix
  xmlns=""
make it difficult to ascertain constraints on the scope of items of the form
  xmlns="<some URI>"
which will in turn complicate copy operations?

independent of questions as to whether the in-scope namespaces
stipulated in the infoset are necessary, if they are to inform such
operations, mustn't the infoset admit all of them? 

i admit that this rehashes questions like those raised in earlier
threads (eg.
http://lists.w3.org/Archives/Public/www-xml-infoset-comments/2001JanMar/0137.html,
http://lists.w3.org/Archives/Public/www-xml-infoset-comments/2001JanMar/0074.html),
but, so far as i was able to follow the related discussions, it did not
appear that the issues were resolved.

- [in-scope namespaces].b

the absence of items corresponding to 'xmlns' introduces unnecessary
special cases into the infoset. a simpler description admits the
presence of that item and specifies that the attribute name encoded as
'xmlns' is associated with an information item which has the prefix
'xmlns'. it is also both simpler and more accurate to incorporate a
designated a value for the null namespace in the domain of namespaces,
for example, the namespace with the name "", rather than to say "there
is none".
