Ok.
The problem is only for a reference to the signature itself.
So, how about adding another Reference element?
For instance,
<!ELEMENT SelfReference (Transforms?, DigestMethod, DigestValue)>
 <!-- The same content as Reference -->
<!ATTLIST SelfReference 
 OmitSignature (all|this) #IMPLIED
 XPath CDATA #IMPLIED
 Id ID #IMPLIED
 Type CDATA #IMPLIED >
- Remove enveloped-signature transofrm
- here() is available only in XPath attribute, and removed from XPath transform.
- Reference is not changed.
(I guess this is an incomplete proposal)
