A couple of comments on section section 2.1.2 (Best Practice 5).

I think it would be a fairly immature XML Signature implementation that 
would still duplicate every namespace node for each element in the 
document. Yes, some early implementations did do that. I suggest 
adjusting the wording in this section as to not imply that every 
implementation does that.

Also, the example uses relative namespace URIs which should be rejected 
by C14N implementations [1]. So the example needs to be changed to use 
absolute URIs. This comment applies to all of the other examples as well.

Note: This specification supports the recent XML plenary decision to 
deprecate relative namespace URIs as follows: implementations of XML 
canonicalization MUST report an operation failure on documents 
containing relative namespace URIs. XML canonicalization MUST NOT be 
implemented with an XML parser that converts relative URIs to absolute URIs.
