# main -> sub1 -> sub2
#     \xtra  \xtra1 \xtra2
# Tests accesses configuration in main/sub1/sub2 and uses grouping
# from xtra/xtra1 for cli/netconf and restconf

# Note that main/sub1/sub2 is same namespace
# Note also that xtra/xtra2 is referenced by same prefix, which stems
# from a problem is that openconfig-mpls.yang imports:
#    import openconfig-segment-routing { prefix oc-sr; }
# while openconfig-mpls-te.yang re-uses the same prefix:
#    import openconfig-mpls-sr { prefix oc-sr; }

# Magic line must be first in script (see README.md)
