If the standard got a "text" attribute tag, then this would be no
problem.  It's essentially the same thing we were discussing before.

Even if the standard didn't have a text attribute tag, it is possible
to use one of the experimental tags for this purpose, but of course
then only GnuPG would be able to use such user attribute IDs.
