Let us solve the simple needs of transmitting a simple document
before attempting to get multipart documents correct! Divide and
conquer.
Let's solve the problems that caused us to start this mailing
list in the first place; those problems include the problems
of properly labelling XHTML with various kinds of embedded
tables, math, markup and use of features.
If XML could only allow you to have simple documents without
any of the complexities of compound mixed features, we wouldn't
have started this discussion in the first place, since it would
be fine just to create a new MIME type for each.
