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 ... ";
           }
