Here
  http://wiki.geda-project.org/geda:gnetlist_scheme_primitives
you can find a "legacy" gnetlist function
 'gnetlist:graphical-objs-in-net-with-attrib-get-attrib'
which was in gnetlist for years. It is used in the drc2 backend:
  - for nc symbols to ensure pins connected to such symbols aren't
    reflected in netlists;
  - and to prevent checking "if pin is not driven" if it has the
    "DontCheckIfDriven" drc directive for those cases where the
    user wants to check if there is no connections of non-compatible
    pin-types and disable some pins from this check.
