Subject: CMP AltCertTemplate control questions

CMP (draft-ietf-pkix-rfc2510bis-02) Appendix D defines the following new 
control:

	id-regCtrl-altCertTemplate OBJECT IDENTIFIER ::= {id-regCtrl 7}
	AltCertTemplate ::= AttributeTypeAndValue

1) Is the complete (expanded) syntax of the control supposed to be

     SEQUENCE {id-regCtrl-altCertTemplate OBJECT IDENTIFIER,
         SEQUENCE {type OBJECT IDENTIFIER,
                 value ANY DEFINED BY type} }

and, if so, what OIDs are expected to be used here?

2) If this control is present and contains both the subject and public key, 
is a POPOSigningKey signature supposed to be calculated on the DER encoding 
of the entire control, or just the AttributeTypeAndValue payload of the 
control?
