Right now, only one XML file is used to build the XML 'model', so if it is missing some XML elements the model will be incomplete. However, if multiple XML files can be read and the union of them used to create the model, then elements that are in one but not in the other will be captured, and the model will be complete (actually, just more complete, i.e. as complete as all the XML files can make it)
This is done. Multiple files will be read in sequentially. Useful for big files where you are not sure if all the XML in the schema is expressed in one file.
