Gets a string representing the version of the document persistence format
supported by the current assembly.
This version is used to check persisted documents' compatibility.
Versions are backwards-compatible, but not vice versa
(i.e. a document persisted using a newer version of C1PrintDocument
may be unreadable by an older version).
