# @CompatPolicy:
#
# Policy for handling deprecated management interfaces.
#
# This is intended for testing users of the management interfaces.
#
# Limitation: covers only syntactic aspects of QMP, i.e. stuff tagged
# with feature 'deprecated' or 'unstable'.  We may want to extend it
# to cover semantic aspects and CLI.
#
# Limitation: deprecated-output policy @hide is not implemented for
# enumeration values.  They behave the same as with policy @accept.
