I agree - we should see if there is any way to avoid creating a new term if
we can.     We just have to be careful not to redefine a defined term.  

Hmmmm

Web Document....   

That works well technically but would an interactive movie be viewed by many
as a document?   I'm afraid 'document' would is too heavily loaded with
paper document concept. 


 

RE your definition of content.  You substituted Web Unit for perceivable
unit.  Can't do that - they aren't  equivalent.

Putting perceivable unit back in you get

Content:  Information in the web unit that is used by the user agent to
generate perceivable units.  This includes the code and markup that define
the structure, presentation, and interaction, as well as text, images, and
sounds that convey information to the end-user.  
 

RE your question
This begs the question, Why not use "resource" (or web resource) everywhere
that delivery unit now appears?
Resources has the same problem as delivery units. 
All Web units are resources but not all resources are Web units
AND most resources can't meet the guidelines.

Browser Page (or User Agent Page) as well as "web document" (or a compound
phrase like "web document or web application") covers example 2 without
having to invent whole new terms, nor having try to explain what is meant by
"unit".

I have read all the excellent subsequent comments.  I think I prefer the
idea of using pages always in quotes over trying to define a whole new term.

> The goal is to replace "delivery unit" throughout with "Web Unit".

Understood.  Is the plan to strike all three (delivery/perceivable/authored
unit) completely, or might they still appear in the glossary?

> So the D U term in content would be replaced as well. 

Right, but assuming we are get rid of three, a straight substitution reads:

Content:  Information in the web unit that is used by the user agent to
generate web units.  This includes the code and markup that define the
structure, presentation, and interaction, as well as text, images, and
sounds that convey information to the end-user.

So again, I suggest it might be instructive to define content without
referencing Web Units.

The most recent definition of Web Unit is nice in that it doesn't reference
content.  It does, however, introduce the new undefined term "resource".
This begs the question, Why not use "resource" (or web resource) everywhere
that delivery unit now appears?
