Adobe Reader/Acrobat is the reference: is you see and print a pdf with
Acrobat under Windows 8 you are on the right side.
Otherwise you are on the wrong side.
For javascript, if the pdf  works under Acrobat under Windows 8 it's ok,
otherwise no.

If Reader/Acrobat doesn't complain the question if the pdf is valid or not
is not important for and end user (ok, it's not true for pdf/a).

Until now I have found the sumatrapdf is (very) good, but it cannot be used
as reference.
