Has anybody used the WMS' Auto projections by which one can provide several 
parameter values?  Is this method obsolete?

BTW, HDF-EOS uses a similar method used in CF-netCDF.  It identifies a number 
of CRS names (codes) and a floating point array for parameter values.

Ethan:
The structure of a URN is so that you can create one - NOT so that theyare parsed for content. I think the fuzziness at the OGC in this regard 
is simple mistaken.
GML is used now in the http://www.epsg-registry.org. This registry and 
the assignment of EPSG codes is controlled by the registration
authority, in this case the OGP. Another such registry could easily be 
deployed assuming that someone is willing to be the registration
authority and this could have perhaps a difference governance model than 
used by the OGP.  The 19111 new parts will make their way into GML of
course.
