!!! Overview
[{$pagename}] is a String that is an identifier for the [SCIM Resource] as defined by the PROVISIONING [SCIM Client].  

The [{$pagename}] may simplify identification of the [SCIM Resource] between PROVISIONING client and [SCIM Service Provider] by allowing [SCIM Client]s to use [SCIM Filtering] to locate the [SCIM Resource] with AN IDENTIFIER FROM THE PROVISIONING DOMAIN, obviating the need to store a local mapping between the PROVISIONING DOMAIN'S identifier of the [SCIM Resource] and the identifier used by the [SCIM Service Provider].  

Each [SCIM Resource] [MAY] include a [SINGLE-VALUE] non-empty "[{$pagename}]" value.  

The value of the "[{$pagename}]" attribute is always issued by the PROVISONING [SCIM Client] and [MUST NOT] be specified by the [SCIM Service Provider].  

The [SCIM Service Provider] [MUST] always interpret the [{$pagename}] as scoped to the [SCIM Client]'s tenant.  

While the [SCIM Service Provider] does not enforce uniqueness, it is assumed that the value's uniqueness is controlled by the [SCIM Client] setting the value. 

See [RFC 7643] Section 9 for additional considerations regarding [privacy].  

[{$pagename}] attribute has "caseExact" as "true" and a mutability of "readWrite".  

[{$pagename}] attribute is OPTIONAL.
