Looking for a sanity check.

WCAG 1.4.4 says "Except for captions and images of text, text can be
resized without assistive technology up to 200 percent without loss of
content or functionality. (Level AA)"

However, Sufficient Technique G142 is titled: Using a technology that has
commonly-available user agents that support zoom. The information on G142
isn't terribly clear as to whether it refers to text-only or full-page
zoom. G142 simply uses the term "Zoom".

"Understanding SC 1.4.4" says:
"The scaling of content is primarily a user agent responsibility." and goes
on to say "The author cannot rely on the user agent to satisfy this Success
Criterion for HTML content if users do not have access to a user agent with
zoom support. For example, if they work in an environment that requires
them to use IE 6."

I personally interpret this to mean that *if* we can be assured that the
user will be on a browser other than IE6, that full-page zoom conforms to
1.4.4. Under what circumstances might we be assured that the user won't be
on IE6? In an environment where the user's browser is dictated by the
organization's IT department.

I interpret it similarly, but consider the IE6 scenario through the
lens of "accessibility support". If someone has IE6, I assume that
they can (except, perhaps, in a closed environment) obtain a more
recent browser that supports the technology, in this case page zoom,
in an accessibility supported way, and that browser is available for
download or purchase in a way that does not cost a person with a
disability any more than a person without a disability and is as easy
to find and obtain for a person with a disability as it is for a
person without disabilities.

In other words, from my perspective, unless we are assured that a user
cannot get access to any browser but IE6, page zoom conforms.
