> Use case:
> A partner company have set up an STS which is connected to their identity
> system. The issued SAML token contain claims in the attribute statement which
> do have a different encoding for the same meaning. Applications should not
> directly depend on the claims because they will be different for each
> partner. Therefore, the application trusts a so called Relying Party STS
> whereas the partner uses their Identity Provider STS. If identities of the
> partners are provisioned into your identiy system you're fine with the
> current IdentityMapper interface but this means claims must be provisioned
> too. This might work for different identity system within the same company
> but doesn't scale with partners. In this case, the RP STS transforms the
> claims of the IP STS to claims which are understood by the application.
> If claims information are correlated to a security token like a SAML token
> it's encoded within an Attribute Statement. If it is a SecureConversation
> token, it's not part of the token itself but locally cached. The claims might
> be encoded within a custom token also.
> The token can be part of the WS-Security header (issue request) or within the
> ValidateTarget (validate request).
> The TokenValidator must validate the token and return the realm which is the
> source realm.
> The claims of the source realm must be provided by the token validator or
> retrieved from the cache.
> The target realm is provided as part of the RealmParser implementation.
> The claims transformation interface looks like something:
> List<Claim> mapClaims (String sourceRealm, List<Claim> sourceClaims, String
> targetRealm)
