That's a good question. When someone from the traditional doc management
biz, like Documentum, says "compound documents" they mean "we can deal
with some number of atomic WP files as grouped into a logical document".
Normally, when browbeating this kind of person, SGML/XML people have
said "a compound document is one with internal structures, like SGML
or XML".  Now we're starting to see documents that are even more
compound, where not only do we have internal structures, but the
internal structures come from different problem domains and DTDs
and information designers - this latter case is the one namespaces
are trying to help with. -Tim
