#100 Add further explanations to InvocationRequested and InvocationRequired

[Martin]

Add notes to the element descriptions what it means to be "required"/"requested" to be invoked? Does the POC MEDICAL DEVICE not work as long as all required operations have been invoked? What does "requested" means? Maybe it is requested to perform a white balancing at a camera system?

[David]

Add notes:
- Required: the intended function of the device/module cannot be executed until the corresponding operations are invoked
- Requested: the intended function of the device/module can be executed but an it is recommended to invoke the corresponding operations

Consensus: Doesn't make sense in a SOA/SODA/SOMDA. Consider forbidding the use of these attributes entirely.

@codimon: Check as to whether this is used in an actual implementation.
@martinuro: Are You happy with scrapping these?

Otherwise we would have to come up with an actual meaning, which is going to prove hard...

[Björn Andersen]

Dräger does not use these attributes.

We discussed some use cases, e.g., calibration of headless providers or required to set a patient weight for therapy purposes.
Heterogeneous opinions regarding scrapping or improving. Fear of forbidding something that is later needed, especially, because the xC-PKP is not yet ready.
Decision: Postpone this topic.
