com.dtrules.mapping.DataMap
The Data Map class holds data for later mapping into the Rules Engine using the same mapping definition that can be used to upload XML to an EDD. This interface can also be used to write out XML to a file.

This isn't a complex implementation. The idea is to collect all the data we would have written to an XML file, then map it in the same way with the same tag structure into the EDD. And as a bonus, we allow for the writing of the data out as XML for debugging or playback purposes. @author Paul Snow
