Is there a way to get an InfoPath form to insert an XML comment in the XML files generated by the form?

For instance, I'd like the main XML element to be followed by a note that we provided this spiffy form, e.g.

<!-- Created with Obvious.xns, provided by (C) Copyright 2012 -->

Or, additional XML comments within other elements could help casual readers of the XML comprehend it

<!-- This section contains all the information about the paradox including the time traveler, and the grandfather to be killed -->

(note that examples are for entertainment purposes only)
