Paint-by-Number (PBN) 0.2 DTD, proposed.
This is a description file format for the logic puzzles known variously by
names like "Paint-by-Number", "Griddler", "Nonogram", "Picross", and "Hanjie".
It is meant to be able to represent several variations, including puzzles with
triangles and triddlers.  Though primary intended to represent the clues of
a puzzle, it can also represent partial or complete solutions to puzzles.
