Well, the state machine definitely thinks that tag names should contain
only ASCII letters (with possibly a leading or trailing '/').  Given the
HTML examples I suppose we should allow non-first digits too.  Is there
anything else that should be considered a tag?  What about dash and
underscore for instance?
