> I'm receiving a response from a (.NET) webservice, where the security requirements are
set by a WS-SecurityPolicy section in the WSDL.
> The response contains a set of Reference elements, thave have both the enveloped-signature
transform and the c14n transform, example below
> {code:xml}
> 	<Reference URI="#action">
> 		<Transforms>
> 			<Transform Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature"></Transform>
> 			<Transform Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"></Transform>
> 		</Transforms>

> Unfortunately, the AlgorithmSuitePolicyValidator does not like the enveloped-signature
transform, and the response is rejected, exception shown below

> I took a look at the AlgorithmSuitePolicyValidator that does the actual validation, and
it scans through all the Transforms, and reject the Reference if ANY of the Transform elements
are not on an approved list.
> Should it not just validate that the list of Transforms contains at least one transform
that is c14n (or similar), and allow the eveloped-signature transform?
