I agree, that does seem nicer.

Another approach would be to deprecate the <import src="url"/> form, so we 
only need to deal with components.  The original src="url" flavor was 
created before schema components had been thought through, and I'd be happy 
to see that go.

Is there some reason not to simply move the section types to a schema 
component?  That seems more in the spirit of making the schema modular.

I've not read the patch yet, so I'll ask:  what's the point of the "type" 
attribute?  Should it be an error if the type doesn't match the top-level 
element of the resource?  If only advisory, is it actually useful?

Thanks for thinking critically about ZConfig.  Yes, I'm aware there are some 
proposals for changes I've not yet addressed.  ;-)
