No.

No. I've considered this in some ontologies I've created (for exactly 
this problem), but it seems a shame to create two properties with 
identical semantics except that the value will be different. In essence, 
this is v:additionalNameIfYouOnlyHaveOneAdditionalName and 
v:additionalNameIfYouHaveMoreThanOneAdditionalName. We surely wouldn't 
want v:additionNameIfYouHaveExactlyThreeAdditionalNames . :)


> 3) We just take away any range constraint on vCard:additionalNames, so one can do both ordering and unordering with a single property

Yes. This was my original proposal and my favorite, although The 
Compromise (1a above) comes in a close second.

No. I agree that some of the same problems crop up, but because 
honorable prefixes and honorable suffixes 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.) I think that, compared 
to names, prefixes and suffixes are sufficiently detached from the name, 
small in number, and reasonably understood semantically not to warrant 
lists.
