True.  My assumption is that over time it evolves into 
a stable set.  In situations where the information is 
highly dynamic or orbits strangely, the utility of  
schemas is questionable and in fact, the utility of  
XML itself degrades.  Initially, one assumes that as 
the document/messages are being designed, evolution 
is rapid and local.  An observable characteristic of 
scale is the tendancy to slow down the rate of change 
given other constraints (costs to field updates, costs 
to create new resources, etc.).  Even when the versions 
are periodic, the rate of change diminishes as the 
coverage becomes complete (the tendancy of an evolving 
system is to take over many niches but that is the 
evolution of the compound document schema; within 
components, the rate of change is slowed).

A catalog documents the operational space (here are 
the languages I use in combination or as isolates) 
which is determined by any number of constraints 
(eg, role, personal preference, etc).
 
There may be a better term for that but I don't have 
one handy.

I think it depends on how dynamic the information is.  If you expect the
catalog to change rapidly, caching the content can cause more problems
than it solves.
