Abstract:

   Definition of the XPS processor. This class is responsible for handling
   the logical document and page structure of the XPS container. The class starts
   with the content types part and .rels part to find the Fixed Document Sequence.
   It then parses the FDS to find the Fixed Documents and finally the FDs to find
   each Fixed Page. Each fixed page is then reported to a client FixedPageProcessor
   to interpret the  mark-up and write out modifications as required. The class is
   additionally responsible for ensuring all XPS parts and accompanying resources are
   sent on to the PK archive handler to be written out.
