We could mandate the qualifier; that would be less thinking space then
leaving it optional.

I think that we got two types in the catalog may be just a design
mistake in our catalog. The alternative is a generic one size fits all
handle; and leave the different "implementations" as ResolveTo targets
:-(

Interesting possibility - so we could leave the URL as the same for
both. And just use the qualifier to "stand in for" the Service=WMS,
Request=GetCapabilities, Vesion=1.1 part ?

At the very least we should do this; so that qualifier is not
optional; and then we can see if we like the result?
