scripts both [tech] and not [tech] (to be or not to be...)

Ok
there were two sections to my email on scripts

The first was a proposal -  That we distil all the individual problems
with scripts authoring to generalizations that can be included in WCAG


The second part of my email was an example of the type of thing it might
include, or what it might look like, to help people understand the
proposal -as a brain dump...

for - it is in contrast to...
 
> > scripts should not create a new dom element

In other words what I am suggesting / asking (this section of the
proposal was just a brainstorm)


Does the DOM need to be populated by the original document for content
to be accessible? 
Is this an inherent problems and what are user agent bugs?

More important perhaps I am wondering about script languages that affect
the integrity of the component model, (for example when the DOM is
created or broken by document.write )  or (even worse) when a script
language or platform does not have component integrity.

If we can address and understand these questions then that will help
designers choose a platform/language for scripting, and , approach
script writing in an accessible manner.

It would also help platform creators understand how to make their
platforms accessible.

That would be really useful.

But probably the first question is, do we want to try and set a
guideline on what is accessible scripting? 

 Can we distil all the individual problems with scripts to
generalizations that apply to WCAG?

Note -I am not talking about when the script's functionality is not
"important" (which we could argue about all day). We can worry about
scoping later. I am suggesting we look at what , from a technical
perspective, brakes a scripts ability to be accessible, possibly  in
what ever form the script is in.
