Sorry to reopen the discussion again, but I had the idea that the
perhaps the SRS attribute in the BoundingBox element is not meant to
define the existence of a new SRS but does only assign the
BoundingBox to a special SRS. Perhaps a SRS should even not be
appear in an BoundingBox element if it is not part of the SRS
element. If there is no BoundingBox for in SRS the BoundingBox would
just be the LatLonBoundingBox projected to the SRS.

Does the spec write something about this relation? At least this
would make sense in my opinion. As a follow-up the list of SRSs
should not be derived from the bounding box elements of a layer, but
only from the SRS element.

What do you think?
