One of the requirements the TF adopted was that authors need to be point to
external long text alternatives. Although I don't buy this requirement, it
does not make sense to say this is required only if the long text alternative
has a structure that can be expressed with markup.

I don't buy the character encoding problem for text/plain, which seems soluble
with out-of-band metadata like content-type (as you note) or sniffing.

We don't appear to have consensus about what @longdesc is for.
