It sounds pretty good to me, if I don't have a way to arrange for all of 
them to supply the same format.

It wasn't our reluctance, but the near (or total) impossibility.  But 
note that in this case, unlike the second vignette I posted, we were 
working to a schema, in fact, two of them - theirs and ours.  The fact 
that their schema itself had some technical errors that I had to correct 
(and informed them about), and that it was a little out of sync with the 
actual delivered format, tells me that they did not have a complete 
process in place for managing quality control.  And this is not unusual.

Here's the thing ... there is no one solution because all the cases are 
different.  XML has a remarkable ability to cope with so many of these 
environments, which is perhaps one reason it has insinuated itself into 
so many places.  In a case where there is a closely connected team, and 
all parties can be forced or pursuaded to use a given schema, you may be 
able to achieve everybody's conformance.

Other cases are more Walter Perry-ish, and that approach is not an 
option no matter how desirable it would be.  And there are all degrees 
in between.
