Partial upgrade to XPS

There are several reasons why a customer may want to upgrade only a few documents to XPS:

1. To simplify the management of templates if there are multiple templates for one given document. One XPS template can be produced in multiple output languages.
2. Need to implement more post-processing actions for one document:
   1. Merging one document with other Mapping or non Mapping documents
   2. Converting one datastream from one language to another (e.g. PDF to XPS and then concatenate with another document)
   3. Etc.
