Filter to insert a pairwise-id that complies with the SAML V2.0 Subject Identifier Attributes Profile .

This filter will take an attribute and a scope as input and transforms this into a anonymized and scoped identifier that is globally unique for a given user & service provider combination.

Note: Since the subject-id is specified as single-value attribute, only the first value of identifyingAttribute and scopeAttribute are considered.
