RequestedAuthnContext exact comparison

Title: Message

In the following 
authn request:

 

<RequestedAuthtnContext Comparison="exact">

  
<AuthnContextClassRef>

    
urn:oaosis:names:TC:SAML:2.0:ac:classes:Password

  
<AuthnContextClassRef>

 

does "exact match" 
specified in Core line 1821 imply an exact literal match against the requested 
authn context class?  Or is implementation dependent, i.e., if another 
authn context class, say un:oaosis:names:TC:SAML:2.0:ac:classes:InternetProtocolPassword, was 
"consider to be at the same level/strength by both parties", would this satisfy 
the exact request?

 

Thanks, Tom.
