Overview
The SubjectDerivedAttribute AttributeDefinition exposes attributes values derived from the Java Subject(s) produced by the authentication flow(s) used to authenticate the subject of the profile request.
In most cases, the SubjectDataConnector is a more useful option because it can produce multiple attributes at once, and the new exporting feature allows them to be used without additional configuration.
A configuration shortcut allows for the values from any IdPAttribute objects contained inside IdPAttributePrincipal objects to be pulled out, which is an effective way to tunnel attribute data from outside the IdP provided by the External authentication flow.

Examples
The following locates an IdPAttribute named "Whatever" in an authenticated Subject and turns it into a new IdPAttribute named "SomethingElse".
<AttributeDefinition xsi:type="SubjectDerivedAttribute" id="SomethingElse" principalAttributeName="Whatever">
The following locates an IdPAttribute named "Whatever" in a Subject undergoing attribute-sourced C14N (such as a proxied SAML login) and turns it into a new IdPAttribute named "SomethingElse".
<AttributeDefinition xsi:type="SubjectDerivedAttribute" forCanonicalization="true" id="SomethingElse" principalAttributeName="Whatever">
