No for YAML.

Causes of non-uniqueness for YAML include
* Booleans have multiple representations (http://yaml.org/type/bool.html
* floating-point values can have extra trailing zeros, and/or could be
  non-normalized (e.g., 1.23e6 and 12.3e5 are two distinct string
  representations of the same floating-point number)
* arrays/lists have two different allowed representations in YAML
