ID-typed attribute on WS-Addressing EPRs?

I notice that WS-Addressing [1] has security recommendations that 
include the signing of elements by those producing EPRs (and message 
addressing properties). Such signing usually requires the presence of an 
identifying attribute on each signed element. I note that WS-Addressing 
does not define any such attribute, but relies on a wildcard for this 
and other attribute definitions. This seems to require that users of 
WS-Addressing must define the use of such an attribute themselves, prior 
to being able to implement the security considerations recommended by 
WS-A. This implies that one cannot use the basic EPR and MAP definitions 
directly from the WS-Addressing specification (if one wishes to sign 
EPRs and be interoperable with anyone else.)

In order to aid interoperability of this specification, and 
implementation of the security considerations within, would it be 
possible to specify the use of an ID attribute within the WS-Addressing 

Perhaps best would be to use the recommendation specified in the xml:id 
specification [2].
