Subject: Re: Punchout in UBL 2.0

thanks for the comment,  but i  am not sure that we  are leaving 
interoperability as "someone else's problem".  it is that we see punch 
out as a tightly coupled activity that is outside UBL's scope as a 
document exchange standard.   we certainly try to address 
interoperability at the document exchnage level.

in case i missed something i will pass this onto our procurement 
subcommittee who may have more to add.
