Determinig Server o Client use in XKMS

Hello,

I'm implementing a XKMS Server and I've a doubt.

My underlying PKI is based on X.509 Certificate, and the problem raises 
when I have to check the KeyUsage and UseKeyWith for the requested Key 
binding in the found certificates. For instance, let be a Request with a 
UseKeyWith for IPSEC with IP A.B.C.D  and KeyUsage Signature and 
Excryption. This is a typical request, but in X.509 Certificate I need 
to know if the certificate is going to be used in a Client or a Server, 
because the necessary extensions are different in either situation.

Then, the question is, how can I determine if a request is for a Client 
or a Server?

Thanks,
