[scim] Referencing individual subattributes in multivalued attributes

[Eric Fazendin <[e-mail]>]

I'm wondering what is the best practice for extracting individual
subattribute values in a multivalued attribute.

Say you had the below SCIM object and you wanted a system to extract the
region value of the home address.  Barring any specific business
requirements, would the right thing be to return a multivalued list of [CA,
KA, KA]?

Related, how problematic would it be to enforce one time use of type for
any given multivalued attribute?  With the below data, the types would need
to be changed to something like home, secondary home, tertiary home.
