--- Comment #5 from Juergen Sachs <juergen.sachs at metz-ce.de> ---
Yes, you're right, we have three different cases
1. *all* Representations have a SegmentTemplate: 
  -> don't do the check (do_sanity_check==0)
    SANITY_CHECK_REASON_NO_SUBTEMPLATES is cleared in the loop
    SANITY_CHECK_REASON_TOPLEVEL_TEMPLATE never set
2. *not any* Representation has a SegmentTemplate 
   (=all Representations don't have a SegmentTemplate)
  -> do the check (do_sanity_check==SANITY_CHECK_REASON_NO_SUBTEMPLATES | \
                                    SANITY_CHECK_REASON_TOPLEVEL_TEMPLATE)
    SANITY_CHECK_REASON_NO_SUBTEMPLATES ist never cleared
    SANITY_CHECK_REASON_TOPLEVEL_TEMPLATE is set 
3. *some, but not all" Representations have SegmentTemplate
  -> do the sanity check
(do_sanity_check==SANITY_CHECK_REASON_TOPLEVEL_TEMPLATE)
    SANITY_CHECK_REASON_NO_SUBTEMPLATES is cleared in the loop
    SANITY_CHECK_REASON_TOPLEVEL_TEMPLATE is set on the 1st Representation 
           not having a SegmentTemplate
Please help me - I do not understand, where the problem is? Can you give a
sample where the algorithm fails?
