		<description>Hello.
I&#039;ve ran into a similar problem, when using WCF. I&#039;ve detailed it in the following post (Microsoft&#039;s WCF forum):

		<description>My understanding is that WCS v1.0 can&#039;t handle multiple issuers, even if those multiple issuers come from a validly formed WS-SecurityPolicy statement.  I haven&#039;t tried it though, and it would be great to get &#039;official&#039; confirmation of the fact.</description>

		<description>FYI I can&#039;t speak for CardSpace, but in theory having multiple, alternative, issuers in theory could be written in the
WS-SecurityPolicy encoding of RP policy.  This is much
more expressive than what can be written in the HTML OBJECT PARAM or XHTML encodings of RP policy.

Quoting section 3.1.1 of WS-SecurityPolicy
http://www.oasis-open.org/committees/download.php/15979/oasis-wssx-ws-securitypolicy-1.0.pdf
&quot;Let’s say that a policy wishes to express requirements for A and (B or C). This could be described as two policy statements ...
Alternatively, we can use the wsp:All and wsp:ExactlyOne elements to describe the alternative policy in a single wsp:Policy element...&quot;

I don&#039;t remember seeing anything in the CardSpace Technical Reference of December 2006
http://download.microsoft.com/download/2/7/c/27c16ebb-bf83-4abd-8002-21fa111ba7ac/infocard-profile-v1-techref.pdf
that said CardSpace 1.0 identity selector&#039;s support of WS-SecurityPolicy couldn&#039;t or wouldn&#039;t support parsing nested policies, though I haven&#039;t yet tried it.
