Let’s continue reexporting jid and minidom, but not their inner pub
items, users of this crate can go one level deeper if they need that.
Only xso::error::Error is still useful to reexport, as this is part of
the public API of all of our parsers.
The specification says it can only be in the 1-256, 4096-4351 ranges, so
use the closest type available. This doesn’t validate that the value is
correct, but that will be done in a future commit.
Thanks gst-meet for making me notice this issue!
