Or the more direct:
when "ancestor::nw:network/nw:network-types/tet:te-topology"
This style works if we can guarantee that there will be exactly one
node "nw:network" among our ancestors.
It is perhaps easier to get this style right w/o a YANG compiler
(which would detect if the number of ".." in the relative path is
wrong), but the relative path might be easier to understand for a
casual reader.
