mapping attributes at the SP

[Mark K. Miller]

Let me preface this by saying I only pretend to run an SP so that I have 
something I can control for testing with my IdP; I'm certainly no SP 
expert.

If an SP is aready receiving a scoped attribute (like 
eduPersonPrincipalName) from an IdP, is there a way for the SP to use that 
to create a new attribute that does not include the scoping information? 
If so, could someone provide an example, or a pointer to an example?

Thank you!
