Relative NS if Exclusive C14n?

Hi All,

short question about the examples in the "Exclusive XML Canonicalization" 
PR:


The section "2.2 General Problems with re-Enveloping" contains this babe:

   xmlns:n0="foo:bar"

My question is:

   Is this a relative namespace?

xmlns:n0="urn:foo" is not, but the above?
