       SippObjectAddSubobj [-flag] objecthandle subobjlist
              Add the objects in the list subobjlist to the spec-
              ified object.  One of the following optional  flags
              may be specified:

                 o  -check  - Validate that adding the subobjects
                 will not cause the object tree to become  circu-
                 lar.  This is the default.

                 o -nocheck - Don't check for building a circular
                 object tree. This option  is  faster,  but  will
                 cause  a  core  dump  when rendering or deleting
                 objects if a circular tree has been built.
