I have added the QNameAware option into the document
into the document. 
http://www.w3.org/2008/xmlsec/Drafts/c14n-20/Overview.html  (August 7th version).  


One thing though the QNameAware parameter is very verbose.

I.e. instead of  <QNameAware>xsi:type, foo:bar<QNameAware> it will be something like this

<QNameAware>
 <QualifiedAttr Name="type" NS="http://www.w3.org/2001/XMLSchema-instance"/>
 <Element Name="bar" NS="http://tempuri"/>
</QNameAware>


However I can't think of any compact notation.

Sorry, cut and paste error. It should be:

"If the prefix rewriting parameter is set, and if the parent element node is
among those enumerated for the qnameAware option, then the QName or CURIE
value of the text node is rewritten with the new prefix."

Sure. What I couldn't do here was show examples with XML syntax for the
option itself, because the XML syntax is left to XML Signature, but we can
certainly express it verbally in an example or two.

No, wsu:Id isn't QName-valued.

No. The thing you're identifying is the element, not the value of the
element. You would only enumerate foo:bar.
