What you ask for is not likely to be available until artificial 
intelligence goes forward much further.  You are asking a computer 
program which knows the *presentation* of a document to correctly 
infer the *structure* of that document, or at least attempt to do so.  

I recently bought Omnipage 9 for Win95 from Caere Corporation.  Among 
all its export formats, it includes an HTML export format.  From what 
I've seen so far, the objective is to make a GUI web browser display 
the page, with fonts, italics, centering, intact.  The HTML is  a 
series of <p> and <br> with Font, I, Align attributes.  No structure.  
It even claims to conform to the HTML 3.0 DTD, and tells you that the 
generator is Adobe Word for Word.  I know that HTML is not SGML.  But 
I'm not too hopeful that when OCR programs begin exporting XML, that 
they will do much better than this. 

I know that Duxbury attempts to create styles in a file which it has 
imported from ASCII, but this is usually just a beginning toward 
correctly marking up a document.  I agree that you're aiming for the 
right objective, but I don't know how we're going to get there.

Linux needs a decent OCR package that can work with a scanner and what is
mostly needed by users of the blinux project is ascii coming out of the
other side of the optical character recognition.
