If we use a comma as a special character, we would then need to 
encode commas, and they are slightly more common in FPIs than
are semi-colons (consider owner identifiers such as "Acme, Inc.").

And anyone confused between a comma and semi-colon should not be
encoding public ids as URNs.

I prefer semi-colons.
