Subject: [OASIS Issue Tracker] Commented: (CAMP-44) Clarify resource type issues and API

...
For example, if type A contains an attribute "address" of attribute type String, which is an IP address; type B also contains an attribute "address" of type String, which is a mac address; and type C inherits from both A and B, then this is considered an error as the constraints of the attribute "address" in type A and B are not compatible.

So now I'm confused, since there's mention of syntax, semantics and constraints in 5.3, and no clear definition (with perhaps the exception of constraints in 5.1) as to what is meant by them. The example given doesn't use attribute constraints, and is identical except that "semantics of the attribute" now reads "constraints of the attribute".
I have other issues with 5.3, but I'll address them once this is resolved.

> There were several key questions about types that have come up in today's F2F:
> What type hierarchy will we use? Mark requests ability to define e.g. MyGreatDatabase which extends Database. (We could also have multiple inheritance / interface / etc.)
> How do we explore the type hierarchy? (The apidoc suggestion in CAMP-1 could come in here.)
> And do we permit dynamic attribute extensions -- e.g. a resource instance has values for other attributes not on its type? (Yes please!)
