How to specify ranges in YAML?

Question

I can express

3rd page is the title page

in YAML

title: 3

What about the following?

Answer 1

Range is application specific. The following may be meaningful for some applications:

-1 .. Q

a .. Щ

23 .. -23.45

1 .. 12:01:14 (both are integers in YAML !)

But the ruby way is also unclear since it does not say whether the end values are included or not: 10 .. 15

(Are you only talking about ranges of integers ?)
