Meta sub-attributes returned in response even when set in "excludedAttributes" #15
Description
The SCIM RFC 7643 for the Meta attribute states that all "meta" sub-attributes are assigned by the service provider (have a "mutability" of "readOnly"), and all of these sub-attributes have a "returned" characteristic of "default". However, all the meta sub-attributes in the BetterCloud implementation are defined with a "returned" characteristic of "always". Due to this, it always returns the meta sub-attributes in a GET response even if any of them are included in the "excludedAttributes" parameter.
The BetterCloud implementation needs to be corrected to set the "Meta" sub-attributes with a "returned" characteristic of "default", to be consistent with the RFC.
