// IsYaml1_1NonString returns true if the value parses as a non-string value in yaml 1.1
// when unquoted.

// Note: yaml 1.2 uses different keywords than yaml 1.1.  Example: yaml 1.2 interprets
// `field: on` and `field: "on"` as equivalent (both strings).  However Yaml 1.1 interprets
// `field: on` as on being a bool and `field: "on"` as on being a string.
// If an input is read with `field: "on"`, and the style is changed from DoubleQuote to 0,
// it will change the type of the field from a string  to a bool.  For this reason, fields
// which are keywords in yaml 1.1 should never have their style changed, as it would break
// backwards compatibility with yaml 1.1 -- which is what is used by the Kubernetes apiserver.
