On Subject/Service ID ranges

One thing I’m struggling with is the term “dynamic”. We’re talking about determining “dynamic” identifiers at system definition time, not (necessarily) runtime; correct? If so then the term really is more used with things that happen at runtime and we should use a different term (e.g. we even have the dynamic node id assignment function). Perhaps static == regulated and dynamic == unregulated?
