I think you're framing the problem incorrectly and torturing yourself 
into more complexity than needed.

But instead of writing another massive email, let me try to identify 
where, in the logical flow, we disagree with one another.

In your flow, here's where I disagree:

Step (*) is imprecise, in my opinion; it mixes abstract and concrete. 
The output of an RDFa parser is, IMO, *a serialization of an RDF graph*. 
That is the key difference, because the "RDF Concepts" definition of 
XMLLiteral applies to the abstract graph, not to all of the graph's 
valid serializations.

Now, help me understand where you disagree with my reasoning. Here are 
two RDF N3 *serializations*:

<> dc:title
"<div xmlns="http://www.w3.org/1999/xhtml">
   foo <b xmlns="http://www.w3.org/1999/xhtml">bar</b>


<> dc:title
"<div xmlns="http://www.w3.org/1999/xhtml">
   foo <b>bar</b>

If I'm reading the XMLLiteral canonicalization process correctly, I 
believe that the two examples above are serializations of the same RDF 

Do you agree? If not, why not?
