 Conventions, containing the files which make up the document. These include an
 XML markup file for each page, text, embedded fonts, raster images, 2D vector
 graphics, as well as the digital rights management information. The contents
 of an XPS file can be examined simply by opening it in an application which
 supports ZIP files.
