{quote}if that is the case why I am able to open this document in any pdf
viewer.{quote}
Viewers often are built to ignore or fix many errors under the hub.
While this may be ok for PDF viewers where the user usually can directly see
whether a repair attempt failed or succeeded, it is not ok for a PDF library
running automatically where the output may be forwarded directly to thousands
of potential customers or be archived in some legal archive.
(Strictly speaking it is *not ok* even for viewers as something wrong might be
shown without being recognizable as rubbish; thus, never trust what you see in
a PDF viewer!)
