I agree that the lack of a public reference is a pain (although some
of us have a reference that doesn't really help you) but I think here
you don't really need a reference as it doesn't depend on the pdf 2
No numeric comparison of minor version makes sense in isolation now
majorversion isn't the constant 1.
Any test of the form
if pdfminorversion < zz do something
needs to be
if (pdfminorversion < zz and pdfmajorversion ==1 ) do something
