The general format of a tag is an introducer, XXX TAG, plus any
number of ASCII-clone characters from TAG SPACE through TAG TILDE.
The first non-tag character ends the tag.

The original proposal allowed for SOURCE CHARSET TAG and GENERIC TAG
as well, but they were dropped for lack of demand. (I further proposed
a split between *public* generic tags, assigned from the reversed
DNS space like Java packages, and *private* generic tags, which could be
anything at all.) In any event, the Tag block still has 31 codepoints
usable for future introducers.
