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?
The docs say we specifically accept HTML tags. Are we really just
accepting anything that is a string of ASCII letters as the tag name?
Then we should adjust the docs. <foo> and <foo1234> are not HTML tags.
I don't think I want to try to maintain a list of exactly which
identifiers are considered valid tag names ... and if I did, I wouldn't
put it into the parser. It would be a dictionary's job to tell valid
from invalid tag names, no?
it'd be nice to know in dictionary the parser state, but I think it's
too much knowledge for dictionary and the only possibility is to
let <foo1234> pass to dictionary. Currently we have three separate tokens.
