Re: yaml-cpp and YAML 1.2

YAML:Node should be parsed differently for the same document:
{ a: true, b: 0x55 }

Failsafe Schema => a and b are strings

JSON Schema => a is boolean, b is string

Core Schema => a is boolean, b is integer

SnakeYAML implements (almost) everything except schemas.
That is why SnakeYAML says it only supports YAML 1.1
If we do not have to respect schemas than many more parsers may become YAML
1.2 compliant.
JS-YAML does support schemas in its API.

Cheers,
Andrey
