Ok, I've updated it based on your comments.

I expect this to be the least rigorously enforced requirement in 
implementations, but from the specifications point of view, this is how we 
make the schema normative:

http://www.w3.org/TR/2000/WD-xmldsig-core-20001012/#sec-Signature
4.1 The Signature element
The Signature element is the root element of an XML Signature. Signature 
elements MUST be laxly schema valid [XML-schema] with respect to the 
following schema definition.

http://www.w3.org/TR/2000/WD-xmlschema-1-20000922/#cvc-elt-lax
Validation Contribution: Element Valid (Lax)
An element information item is laxly schema-valid if either
1.1     The item is strictly schema-valid as defined by Element Valid 
(Strict) (§3.3)
or
1.2.1   The [local name] and [namespace URI] does not resolve to an element 
declaration, as defined by QName resolution (Instance) (§3);
1.2.2   All the element information item [children] and [attributes] of the 
item are laxly schema-valid, as defined by this constraint or Attribute 
Valid (Lax) (§3.2), respectively.
