Suggestions for a change of the sticker specs

[Damien Roux]

I also would like too add:

Do we need condlines on the back face of a formed sticker, and on it's edges?
I got the problem with 821472hc01 (have a look on the tracker).


Do the pattern codes letter restrictions (i, l, p, etc..) also apply on stickers code?
(If yes, there are official stickers not respecting it).
