1) I was overly terse above, and at least one other respondent has not
unreasonably misunderstood -- I should have said "any sensible use of
QNames _in content_ . . ." (as opposed to for element and attribute
names).

2) I guess what I'm saying is that I'm betting that applications which
find QNames in content useful will also find that type-enriched
infosets are useful too, and be willing to pay the price of getting
them.  I understand that you're betting the other way.  Time will tell.
