should be:

> <Apply FunctionId="ext:get-public-key">
   <Apply FunctionId="ext:keyInfo-one-and-only">
>    <SubectAttributeDesignatorWhere AttributeId="urn:....:key-info">
>       <SubjectMatch MatchId="function:string-equals">

   </Apply>

where ext:keyInfo-one-and-only takes a bag of ds:KeyInfo and returns a
ds:KeyInfo if and only if there is only one element in the bag,
indeterminate otherwise.
