PubDIDs (and DIDs in general, maybe)

[Arnold Rots]

The question is not so much what the best way is to do this.
It would be perfectly fine, I think (and even better), if
   ivo://ADS/Sa.CXO#obs/05285
were written as, e.g.,
   ivo://ADS/Sa.CXO?type=obs&obsid=05285
since it would make resolving the URIs much simpler.
However, the issue is that there are tens of thousands of persistent
identifiers in existence that need to remain persistent.
