# Yang features. if-feature.
|
|
# The test has a example module with FEATURES A and B, where A is enabled and
|
|
# B is disabled.
|
|
# It also uses an ietf-router module where (only) router-id is enabled
|
|
# Also check modules-state (RFC7895) announces the enabled features.
|
|
#
|
|
# From RFC7950:
|
|
# 7.20.1 Schema nodes tagged with an "if-feature" statement are _ignored_ by
|
|
# the server unless the server supports the given feature expression.
|
|
# 8.1: There MUST be no nodes tagged with "if-feature" present if the
|
|
# "if-feature" expression evaluates to "false" in the server.
|
|
# - Should the server just "ignore" these nodes or actively reject them?
|
|
#
|
|
# Clixon has a strict implementation of the features so that setting
|
|
# data with disabled features is same as if they are not present in the Yang.
|
|
# Which means no cli syntax or edit operations were syntactically allowed
|
|
# (and therefore invalid).
|
|
|
|
# Magic line must be first in script (see README.md)
