I think I'm missing context here but...

It would be good to have this in an RFE otherwise it will get lost.

> 1)      Required: PrincipalClass:  What principal class to extract out of the subject.   
Is there ever any case when you want more than one principal class?

> If there are multiple matches this logic will be called multiple times once per instance.    
> Assumes Principal also has an interface which allows get(String), and 
> Set<String> getKeys().

I'm not sure the relevance of this, but I suspect it comes out in the code.

> 3)      Optional: Attribute list - list of attributes to return or return all if not listed
> 4)      Optional: ReturnAttributes change the name of the attributes on return to those specified.

Without understanding more this seems weird.  In your example you seem to be making an assumption about what a Principal is which transcends java.security.Principal (is youe example X509 specific?
