Hi Jeremy,

I ran your c14n-impl awk script [1] against the ntc test cases [2] and
found that it breaks on three tests: 003, 011, and 012. 003 can be fixed
by filtering the output through "uniq". 011 uses bNode predicates and
can therefore be dismissed. 012 on the other hand seems to be failing
because your c14n:true "intert triple" hack [3] isn't implemented. Are
you planning on implementing this in the c14n-impl awk suite? It would
be nice to use it as an independent GI utility for testing RDF APIs.
