RE: GL 2.5 L2 SC2

I had an action item to write a SC for this Guideline that would "Help users
avoid mistakes"

The Guideline says: 

"Help users avoid mistakes and make it easy to correct them."

Yet we have no SC to address helping users avoid mistakes. I am hoping to
come up with something that is testable. I think it is important to help
users avoid mistakes and I think it is too bad we don't have any SC to
address this. I will keep bouncing it around and see if I can come up with
anything. (An ounce of prevention....)

If we have no SC to address preventing errors, then perhaps we need to pull
the first part of the line from the SC "help users avoid mistakes" if we
can't offer any SC to address that. That would be a shame, I think.

I did about 4 days work on this Guideline for the Guide Doc, a few months
ago. Several Accessibility consultants, well respected in the field,
recommended me some excellent techniques to help users avoid mistakes and I
think that would be a shame if we can't find a place to legitimately hang
them so they will actually be used, rather than sitting in an optional pile.

The items are at:
http://www.eramp.com/david/general/


There are 10 techniques there and they are currently all in the optional
pile.

One technique that has no home yet is:

(2) Do not use the same words or letter combinations to begin each item of
the list.	(I think this a very important technique that has no home
yet and is not in the techniques anywhere)

Not sure I understand your question - but the sufficient techniques have to
respond directly to the success criterion requirements.  In this case -
things to do when the content/server detects an error by the user.   (some
of these look preventative rather than responsive.  Those are good ideas but
not required by success criterion.

Follow?

Hmm. I guess we need to say something like

"Providing a text message that identifies the field as mandatory"

These are all meant to identify what suggestions to provide, and would
presumably use the same techniques as GL 2.5 L2 SC1 to report to the
user. Should we explicitly refer to the error reporting techniques from
that SC?
