PubDIDs (and DIDs in general, maybe)

This was just pointing out that the vospace uri scheme is specifically 
to have globally unique resolvable identifiers. In the details, the vos 
scheme defines the resolution rule so that it does not clobber query 
strings or fragments or other such things that the vospace spec may 
define or a specific vospace service may want to implement.  The vos 
scheme splits between the authority and the path. That is a compelling 
feature of the design.

One can get globally-unique easily enough; resolvable requires some 
rules, and no-clobbering restricts the rules.
