Hi Jonathan,
as said above, using "version" in GetCapabilities is a GeoServer vendor
extension, it's not part of the OGC specifications.
As such, it's free to behave as it pleases when you use it.
The version negotiation protocol is described in the various OWS documents,
each version of a protocol
is based on a different version of OWS, e.g., WCS 1.0 is probably based on
1.0, WCS 1.1 still probably
based on OWS 1.0 but not sure, WCS 2.0 I believe is based on OWS 2.0 (fun
fun):
http://www.opengeospatial.org/standards/common
Go look for "GetCapabilities request KVP encoding" or something similar to
find the requested behavior
Cheers
Andrea
