Ah, that's why I picked expat, instead of the more convenient DOM
implementations (which are huge).
On x86_64, libexpat.a is 600K, with debugging information enabled.
Code size is only about 140K of that. For comparison, remote.o is 70K
code size and 280K with debug info. So it's two to three new files
worth of code - in my opinion, this is an acceptable cost. What do you
think - workable?

Not particularly. Expat 2.0.0 was released in January 2006, so it's
still maintained, but there haven't been any releases since then, so
it's not churning particularly. I don't think it likely that we'll
need any cutting edge features from it, either. My plan was to import
2.0.0 and leave it alone as much as possible, unless we encountered a
bug in it.
