That's actually:

Sounds good.

So just to be very clear, the XML literal is exc-c14n as if it were its own 
distinct fragment? So even if a namespace/prefix is declared above in the 
RDF, it will be repeated in the XML literal.

The second fragment after the "and" confuses me.

I still find this section confusing. For example, "The XML document 
corresponding to a string str is formed as the XML document corresponding 
to the pair (str, "")." This is a restatment of the earlier statement, "The 
XML document corresponding to a pair ( str, lang ) is formed as follows:" 
which leads to confusion.
