Lift additional RetrievalMethod type values from RFC 4051?

RFC 4051, section 3.2 defines a number of additional RetrievalMethod  
Type values, some of which correspond to elements in XML Signature.

Shall we lift any (or all) of these into XML Signature 1.1?

Should they be covered in the algorithms cross-reference?

Thanks,
