Hi

Some of the SID BEs have attributes stereotypes with <<required>>

Does this imply that:

1. All BE attributes stereotyped with <<required>> have a [1..1] multiplicity (i.e. mandatory)?
2. All BE attributes NOT stereotyped with <<required>> have a [0..1] multiplicity (i.e. optional)?

If this is the case, then why is the <<required>> stereotype being used rather than the use of UML multiplicity - similar to the associations and aggregations? Or is the <<required>> stereotype another standard way of doing it?

Also, some BEs do not have any attributes with the <<required>> stereotype. does this mean that ALL the BE attributes are optional?

Thanks in advance

Hi @Gary Wilson,

The "required" stereotype on SID attributes is used for conformance purposes.

As you might know, a Software provider may ask to TMF to check their conformance to SID (it might concern a sub-list of ABEs).

So when an attribute is "required" it means that if the Software don't have this attribute , the conformance will be KO.

Some attributes might be considered as optional (without any stereotype) meaning: good to have but not essential.

See you,
