Property Level
Level
Gets or sets the conformance level to validate against. When
null (the default), the level is resolved from the document's
own PDF/A identification: a file declaring part 1, 2 or 3 is
validated against that part's B profile, and a file declaring
nothing is validated against
PdfA2b (and fails the
identification rule, as an unidentified file is not a PDF/A file).
