Genx c14n?

I think we're getting to the point where the most productive next step 
is to implement the library and see how it works in practice.  Except 
for one issue:

Q: Should genx produce canonical XML output?

I've worked on a couple projects in recent months where the XML 
messages would sometimes or always need to be signed, and I'm 
developing the general feeling that the world holds a *lot* of dsig 
technology; in private correspondence with some folks here I've heard 
horror stories about what people do to get canonical XML: parse, load 
into DOM, reserialize (a horror story in a high-volume app).  So I had 
the impression that if genx produced canonical XML that would be A Good 
Thing particularly if the cost was low.  The idea doesn't seem to be 
getting much of a welcome here.

Would anyone like to take this opportunity to shout "Yes, the world 
needs this!" or "No, the denominator of the cost/benefit ratio is 
zero!".
