Hello,
a client sent to us a PDF with a strange xref table. Here is what it looks like:
xref
0 55
%% standart xref entries
200001 5
0000052507 00000 n
0000052793 00000 n
0000053079 00000 n
0000053365 00000 n
0000053727 00000 n
trailer << /Size 55 /Root 54 0 R /Info 53 0 R >>
startxref
54691
%%EOF
Those extra five objects are well formed link annotations. According to the standart, I should ignore those objects but all the tools I used to inspect the document found no problem in it.
So what should I do: concider /Size as the upper limit for object numbering in the document, or reach every reachable object, no matter what its object number is ?
