A single cell is not valid though, right?

This particular property is problematic because each entry depending 
on the platform has different number of cells (5, 6, etc.). A single 
cell (minItems: 1) is not valid though, right?

There's a fix in dtschema min branch which should fix the warnings. 
Unfortunately, it just strips any bounds checking.
