thoughts on issues 6 and 19?

Issue 6:

Classification: Understanding WCAG Document, How to Meet SC 4.2.1-Intent
  of this SC [1], Editorial Comment

Original Comment:"in the GL list Wendy posted the following explaination that
I think would be good to add to the intent section to explain.
John suggested an edit which is also included"

Proposed Change:"WCAG 1.0 says "If you can't avoid building stairs, build 
an elevator."
  It doesn't say anything about making the elevator easy to find or get to.
SC 4.2.1 of WCAG 2.0 says, "If you can't avoid building stairs, provide an 
elevator at
  the main entrance, along with the stairs."

Recommended Response: May need some more discussion?  Accept premise of 
proposed change,
  but should testability of "easy to obtain" be considered (or is this out 
of scope for this
discussion)?  NOTE: What is "easy" for
some users may not be "easy" for others.  In the elevator example, perhaps 
it would be
good to provide "directions to
the elevator" right at the main entrance, so that one could not avoid 
encountering these
directions (in a variety of renditions to address particular accessibility 
needs)
at the main entrance.  Maybe should state "The elevator should be at least 
as close
to the main entrance as the stairs are.  Or, the elevator should be at 
least as
"prominent" (noticeable?) to a user at the main
entrance as the stairs are."  The idea is that the accessible solution 
should be at least
as prominent to a user as the nonaccessible solution, or is that going too far?


Issue 19:

Classification: WCAG 2.0 Draft, SC 2.4.2 [2],  Technical Comment

Original Comment:"Are there "processes" which are not "tasks" for purposes 
of this criterion?
I can't think of anything that would qualify. If I perform an interaction 
in a user
interface, surely I am performing, or undertaking, a task and the result of 
my doing
so will be the result of the task performed.   If this is right, then make the
change proposed below."

Proposed Change: "Change "process or task" to "task" or "task performed by 
the user"."

Recommended Response: May need some more discussion?

  Definition of "process" (from Webster's New Riverside
Dictionary) is: "a system of
operations in producing something", or "a series of actions, changes, or 
functions that
achieve an end or result"

Definition of "process" (from [3]) is: "a series of actions, changes, or 
functions
  bringing about
a result", or "a series of operations performed in the making or treatment 
of a product".


Definition of "task" (from Webster's New Riverside
Dictionary and from [4] - identical definitions) is: "a system of is:
  "a function to be performed; an objective" (also
"a piece of work assigned or carried out (done) as part of one's duties", or
"a difficult or tedious undertaking"?).

  NOTE that "function" (definition of "task") appears
as a choice in a definition of "process" previous, so "task" might be 
considered
  a subset of "process"?
Thus, from these definitions, "process" and "task" may seem different in scope?
Or, more to the point, how specific do we want the applicability of this SC 
to be?

Thanks and best wishes
