My pleasure, but you have to clean up the English yourself:-(

Yes, lets have dimensions.  As to the details, well... If we have a 
serious of page-scans of the same size, it would surely be enough to 
have one <dimension> child on <facsimile>.  Otherwise, if we have 
<surface> elements to provide for multiple graphics, I'd suggest a 
<dimension> child there as well.
