John-
I attempt a response, but I am anything but an expert in CRSs. CRS
handling in WCS (which is based on GML 3.1 currently) is based on both
identification (via URIs) and explicit indication.
For the latter, a transformation can be indicated as part of a
coverage's spatiotemporal domain definition, see Table 13 of WCS 1.1.2
(OGC 07-067r5). A transformation provides georeferencing coordinate
transformation for unrectified coverage according to
CC_CoordinateOperation, see ISO 19111^
...in cases when the coverage is not given by a GridCRS - see WCS doc
for details.
I would like to think that such a transformation can do the trick for
your cases as well, but as said I'm not the expert in this.
Hope it helps, though,
Peter

Hi Ron, Peter, et al:
I think what follows is the same issue that Aaron brings up, or at least a
small part of it.
Our data typically uses CRS that are described by parameterized projection
functions. eg, Lambert Conformal, with parameters lat/lon origin and two
standard parallels. Thus there are an infinite number of possible CRS. Is there
a way to map that into an EPSG code and/or form a URN?
apologies if this is obvious.
