Yes, and my copy matches
I guess you fixed it after submitting the draft.

Well... not knowing what it means, my guesses are:
- The same syntax, but further restricted by e.g. size limitations,
- 'Refining' e.g. a DirectoryString to PrintableString, which is
one of the ASN.1 CHOICEs for DirectoryString.
- Allowing either of the above.
If you feel it's OK to leave it at that, that's fine with me.
If not, but people should look up X.500 for 'syntax refinements',
perhaps you should add an X.500 reference.

If "it" = "the rest": No, that's now UALPHA.
Which is not consistent with the other tokens in these definition
formats; they are case insensitive.
