What would be the "corner cases"?
{quote}

E.g.

* Should the *ArtBox* be used instead of the *CropBox*? After all the art box 
is the _extent of the page’s meaningful content_... But on the other hand 
people might want to get all visible content nonetheless.
* Should tagging be considered?
* Should the *UserUnit* of the original page be taken into account?
* Should the *Rotation* of the original page be taken into account?
* Should the *Group*  of the original page be taken into account? Consider e.g. 
knockout group pages.
* Should the *X* of the original page be taken into account? (*X* being any 
other page dictionary entry)
* Should really all resources be copied? (There are documents in which there is 
only one resources dictionary inherited by all pages, containing all resources. 
For them too much would be copied here.)
* Many PDF viewers can only process xobject nesting up to a certain maximum; 
what if by this method the nesting maximum suddenly is exceeded?
* ...
