In Business work 6, how to send "holder of key" for SAML policy.

[ankit aggarwal 4]

We are evaluating Tibco business work, if it suites our need. But seems it is not fully capable of handling things.

While calling external soap server, we want to add the holder of key in SAML policy in policy, but it always send "sender-vouches".

 <saml:SubjectConfirmation Method="urn:oasis:names:tc:SAML:2.0:cm:holder-of-key">

instead of

<saml2:SubjectConfirmation Method="urn:oasis:names:tc:SAML:2.0:cm:sender-vouches"/>

Also, how can we add custom attributes in policy. There is no option and not given in any documentation.
