# Creates a policy to validate the params hash against the given schema. See
# {Schemacop::Validator} for more information on how schemas are built.
#
# Schemas are always validated on instantiation and, using defaults and
# casts, can also alter the params hash assigned to the operation.
#
# Only one schema can be active at a time. Defining multiple schemata or
# defining schemas in a subclass always override previously defined schemas.

# @param *args [Array] Parameters to pass at schema initialization
# @yield Block to pass at schema initialization
