Pattern sequence should contain strings, singletons of form [string] or PDFPatternIf objects. Strings are literal strings to be used in the object. Singletons are names of keyword arguments to include. PDFpatternIf objects allow some conditionality. Keyword arguments can be non-instances which are substituted directly in string conversion, or they can be object instances in which case they should be pdfdoc.* style objects with a x.format(doc) method. Keyword arguments may be set on initialization or subsequently using __setitem__, before format. "constant object" instances can also be inserted in the patterns.
