Sorry, but that just isn't true. If you read the TWAIN specification at
the URL that Carl provided, specifically the opening paragraph of
Chapter 3 entitled "Application Implementation" where it spells out in
detail whether you need capability negotiation and what the limitations
between scanner and application will be if you don't use it.

It all depends, firstly, whether or not your application proposes to
use the UI of the scanner's Data Source (DS) or not. If so, you can
probably forget about capability negotiation. If not, then it all
depnds on what your application proposes to do; but if you want any
kind of control over the images, capability negotiation is going to be
pretty important.
