Before trying, the first page can be included in a box, then
\pdflastximagespages is available for testing whether the
intended inclusion page is valid. (Documents with zero pages
cannot handled this way.)

Instead of checking two dimensions, it should be easier to check
whether the page is not greater than \pdflastximagepages.
Then no funny value is needed for the dimensions, 0pt, 1pt, 1bp,
1in can be used.
