My problem with this two document system is that I have to use one document but check a second document to see if the first one is correct or not. Surely, producing the "changed" document is as much work as changing the existing document.
I don't see how it saved money, time, trees, the environment, anything. I do see how it will confuse and annoy people.
Can anyone explain the advantage of this system except for faster download speeds.
Edit, one more thing. I recently needed the data sheet for the 16F727 and assumed that the data sheet labeled 16F7x7 would cover it. Wrong, it's covered by the document titled 16F72x. Did nobody consider this when naming the parts/documents.
