How would you have proposed that XML's developers create a
MIME-compliant form of content labelling?  

Or would you simply have banned the notion of mixing different
vocabularies into a single document?

Anything with only two levels is pretty well guaranteed to run into a
need for three or more.

MIME is a legacy technology.  It works well for what it did and does. 
That doesn't mean it'll work well going forward.  (And the same may well
happen to XML over a similar period of time.)

No, they're not very efficient.  I'm not convinced however, that sending
XML over separate pipes is particularly sensible either.
