[Fiware-ngsi] Clarification on NGSI10 binding document section 3.1.2

[Fermín Galán Márquez]

Dear Tobias,

The following is said in section 3.1.2 in NGSI10 binding document (PUT for ../contextEneitites/{entityID}):

"In case that a submitted ContextAttribute does not contain a value ID in the form of metadata, or if the contained value ID does not exist in the system, the respective
ContextAttributeResponse instance SHALL only consist of an error message."

If I'm understanding correctly, that writing is precluding the usage of this convenience operations in simple scenarios when "multi source" attributes are not used (i.e. ID metadata are not used), e.g. just one temperature sensor registered without ID. Is my understanding correct?

In positive case, I would suggest to make this convenience operation more flexible, using the following wording:

"In case that a submitted ContextAttribute contains a value ID in the form of metadata and the value ID does not exist in the system, the respective ContextAttributeResponse instance SHALL only consist of an error message"

What do you think?

Thanks!

Best regards,

------
Fermín
