WPC: General questions

[uvo]

Regarding notation, if two different notations are globally used, one is complete but the other is not, is it valid or not?
For example, in dissection puzzle, what if dissection is complete but connecting lines miss a segment?

If one notation is complete and correct, the solution is considered valid, regardless of anything else.

I have to amend my last statement: If one notation describes the correct solution and there are other incomplete notations, then the solution will be accepted. However. if there are two (or more) complete notations that describe different solutions, then the puzzle will be marked as incorrect.
