Andy914's right - TimP you can design your form and then save an example of it and then look at the XML. You'll then see where the text goes for the title, version, and comments. I don't know where your original data is coming from, but it's just a few
scripts away from turning those into %1, %2, %3 fields to be printed one by one into individual XML files.
If your data is in a database that InfoPath can hook up into, though, I'd say go that route because then you can have they users query for a particular title, update, and save back into the DB.
One big hint in the design of your form: perhaps you want to take all of these responses and merge them into a single document? If so, make sure you design your form so that the title, version, and comments is a repeating structure (you can add more than one,
even if you're just editing one at a time) so that you have that merge opportunity in the future. Given the merge, you can even go and easily export / import that into another application for analysis, reporting.
Give it a test run! I'm certainly interested in hearing how it goes.
