Folks,
I have posted a little question about TMS spec to the standards,
but perhaps I could receive some feedback here as well:

Folks,
I'm reading the TMS spec which says:
"a coverage of regularly sized and spaced images that taken together
form a complete visual representation of the entire area of coverage"
I understand the size and spacing constraints.
What I'm missing, however, is what TMS says about "topological"
regularity of tiles within a coverage.
I attached basic drawing with two example tile coverages:
a) blue - regular coverage, rectangular
b) red - irregular coverage
Is only blue version kosher for TMS or both versions are valid?
Best regards,
