Comparing PDF's disregarding comments

[MiniMe]

Hi there,
I'm looking for a solution to my problem.
I could not find appropiate answer by using the search,
If I was just to stupid to find them, please point me in the right direction.

I would like to compare 2 pdf-docs. The older file usually has comments (either text or image, e.g. hooks, x) made by the user.
When comparing the old (marked) file with the new (unmarked) file I want BC only to compare the original file without comments to the new file.
Do you have any idea whether and how that might work?
I'm using BC4

Define the differences you want ignored as unimportant text.
