I wonder if you can help me with a when in a grouping; where does grid-type in
when come from below?
ccamp-wson-27 has (slightly edited)
augment "/nw:networks/nw:network/nw:node/tet:te/"
+ "tet:te-node-attributes/tet:connectivity-matrices/tet:label-restrictions/"
+ "tet:label-restriction/tet:label-step/tet:technology" {
when "../../../../../../../nw:network-types/tet:te-topology/"
+ "wson:wson-topology" {
description ...";
}
description ...";
case wson {
uses l0-types:wson-label-step;
}
}
with a tree diagram
augment /nw:networks/nw:network/nw:node/tet:te
/tet:te-node-attributes/tet:connectivity-matrices/tet:connectivity-matrix/tet:from/tet:label-restrictions
/tet:label-restriction/tet:label-step/tet:technology:
+--:(wson)
+--rw (l0-grid-type)?
+--:(dwdm)
| +--rw wson-dwdm-channel-spacing? identityref
+--:(cwdm)
+--rw wson-cwdm-channel-spacing? identityref
while l0-types has
grouping wson-label-step {
description "Label step information for WSON";
choice l0-grid-type {
description "Grid type: DWDM, CWDM, etc.";
case dwdm {
leaf wson-dwdm-channel-spacing {
when 'derived-from-or-self(../../grid-type,
"wson-grid-dwdm")'
{
description "Valid only when grid type is DWDM.";
}
type identityref {
base dwdm-ch-spc-type;
}
description ...";
reference ... ";
}
}
case cwdm {
