Re: A testability example

Hello Lisa,
Fundamental issue: Does this not impinge on the author's  choice i.e.
writing style, selection of words / phrases etc.?
Yes words have synonyms  but very often there is a nuanced difference
between one word and its synonym.
When one adds an alt to an image,  the image does not go away but one
who cannot see can at least  have some understanding of what the image
represents, its purpose in the context of its use. Surely without
vision one cannot perceive or appreciate the  asthetics of the
graphic.
Likewise,  adding markup so that content that looks like a list is
exposed as a list to AT or  adding TH-TD relationship to a table does
not change the look and feel of the original content for non-AT users.
But for instance, conforming with SC 2.4.10 i.e. inserting heading
text where none exists does change the content and is a AAA level SC
that helps users with learning disabilities / vision impairment.
So, one may require use of simple, more common  words etc. as
proposed, say, in an alternative rendering of the content. Is that
what the proposed SC suggests?
Or am I missing something?
Thanks and best wishes,
Sailesh Panchang
