I think you are talking about requirements? Some of the combinations you mention are for requirement declarations (at the node type) and some for requirement assignments (at the node template).

Generally speaking, ARIA intends to support 100% of the TOSCA spec, so feel free to contribute. If a combination does not work, it is a bug.

There is a known bug about requiring a capability without a template that is being worked on.
