like that this forces UI choices, but that seems to be the goal here so
maybe some language allowing for lists, predictive completion, etc?

It *does* sem a little confusing at first, but there are actually two
different requirements here:
(1) If there are 75 or fewer options, then there *must* be a select list
of some sort and there *may* be a text-entry field as well;
(2) If there are more than 75 options, there *must* be *both* a
text-entry option *and* a select list of some sort.

(Hmm, how about *that* for wording...?)
Jason's comment earlier today suggests that we may be more HTML-specific
than we intend here-- he notes that XFORMS allows for different ways of
presenting the functionality.  So perhaps this is really a fallback
*technique* rather than a success criterion after all.

And Jason raises an entirely different (and much more serious) issue
when he challenges the separation of content guidelines from user agent
guidelines...

It is a bit long though.  Anyone see how to shorten it without changing

OK, I'll bite. Here's another pass-- two items, total of 52 words (down
from 84).  May be too cryptic, though.

When user input is limited to a set of known choices that can be
provided without risking security or purpose, choices can be selected
from a list.

When user input is limited to aset that contains more than 75 choices,
choices may be selected from a list or entered by the user. </proposed>

Subject: Gudeline 2.5 Level 3 SC work item


Yesterday, I took a work item to clarify Guideline 2.5 Level 3 SC number
1 to make it clear that selection lists of more than 75 entries should
be accompanied by some other means of providing the input so that screen
reader users are not required to listen to all items in a huge list in
order to provide input.

Current wording:

1. Where text entry is required for which there is a known set of less
than 75 valid choices and they can be provided without jeopardizing
security or purpose, users are allowed to select from a list of options
as well as to type the data directly.

Proposed wording:

1. When user input is limited to a set of known choices and they can be
provided without jeapordizing security or purpose, users are allowed to
select the choice from a list instead of, or in addition to, typing. If
there are more than 75 choices, selection lists must not be the only
means of providing the input choice. Another input method, such as a
text entry field or a search function, must be provided instead of, or
in addition to, the selection list.
