This module allows you to declare Moose type constraints to validate nested data structures as you may get back from a JSON web service or something along those lines. The doctype declaration can be any arbitrarily nested structure of hashrefs and arrayrefs, and will be used to validate a data structure which has that same form. The leaf values in the doctype should be Moose type constraints, which will be used to validate the leaf nodes in the given data structure.
Declares a new doctype type constraint. $name is optional, and if it is not given, an anonymous type constraint is created instead.
