Note to clarify, this proposal would allow additional unordered names,
as in unordered lists of names. TimBL seems to prefer this to be
restricted to a cardinality of 1, but my original proposal in the e-mail
does not restrict the cardinality.

I think TimBL's response shows that suffixes and prefixes suffer from
ordering issues, i.e. "Herr Professor" and so on. One could say "*names*
are almost a known universe, a processor can easily present the correct
order when needed. (In fact, the order may vary among locales---I don't
know.)".

Also, the vCard spec [1] itself seems to think they are ordered.
