[cddlm] CDL: scope of names

I just want to make sure that I am writing the correct tests here, and want to ask some questions about resolution Is it true that 1. you cannot have the same name in cdl:configuration, cdl:system and anything we imported without giving a namespace 2. when we resolve things, you can have a forward reference from cdl:configuration to cdl:system 3. you should use a prefixed reference to resolve to a name in a different namespace. I am also confused about the implications of #3. -should the default namespace be (a) something you specify with cdl:targetNamespace on the <cdl> document (b) what you declare with any schema declarations. Answers welcome. Oh, how I despise XML namespaces. -steve
