Re: [ebxml-cppa-negot] updated message content

Bob,

Thanks.  I was not aware of that tool.

The situation is this:  If I prepare a CPA template to send you and it is
mostly based on the CPA template that you put in the registry, there are
two different things going on:
   I tell you in the NDD what is negotiable.
   I may have also modified other information from your CPA template but
   not made those items negotiable (not included in the NDD).

It's (2) that I hand in mind in my original suggestion. A diff tool will
give the combination of 1 and 2, which is probably sufficient.

However there is another answer which this discussion awakened in me.
Perhaps when I receive an offer, I should forget about what I might have
published as a CPA template and simply analyze the offer. In that case, my
original suggestion is not useful.

Is anyone else looking?

Regards,
Marty

I meant XML diff.  See below.

Google has lots more, but I thought I'd reference
your cohorts.

It's easy to make a mistake.
I'm honorable, but not always precise...
