Scoping can include and exclude parts of a site.  However processes and
authored units must be evaluated in their entirety.  If part of a
process unit does
not conform (at some level), than no conformance (at that level) can be
made for any web unit in the process.  The same applies to authored
units.

It was pointed out that the second sentence in the following was almost
unreadable.

 

Scoping can include and exclude parts of a site.  But if any Web unit
that is part of an authored unit or part of a process or does not meet
WCAG 2.0 at some conformance level then no Web unit that is part of the
authored unit or part of the process can claim conformance at that
level. 

 

 

Suggested rewording:

Scoping can include and exclude parts of a site.  However authored units
and processes must be evaluated in their entirety.  If part of an
authored unit (or a process) does not conform (at some level), than no
conformance (at that level) can be made for any web unit in the authored
unit (or the process). 

 

Still a bit complicated.   Could break it up further.

 

 

Scoping can include and exclude parts of a site.  However processes and
authored units must be evaluated in their entirety.  If part of a
process unit does not conform (at some level), than no conformance (at

applies to authored units.

Subject: Scoping clarifications

 

In putting together all our decisions into the Introduction and
Conformance sections - I found that we don't have any wording for a few
things that I think we decided. Below are three things - that if we
agree on - should be clear in the last call document. 

 

 

1)       We intend for a page to be accessible without requiring that
all links on a page lead to accessible content.  (otherwise one could
never link to content out of their control). 

2)       We want to allow people to separate content on their website
and make claims for some but not all of it.  (someone else may require
accessibility but we do not).

3)       We also decided that a process shouldn't be accessible up to
its final stages and then go inaccessible.  Like everything in a store
but the checkout.  

 

 

To fix this - I am suggesting that we add the following  to our scoping
section  which currently reads 

 

 

 

<current text>


Scoping of conformance claims 


Conformance claims can be limited, or "scoped," to pertain to only some
parts of a Web site. All conformance claims, however, must be directed
to a URI or a range of URIs. Scoping to exclude a particular type of
content (for example, images or scripts) from a site is not allowed
since it would allow exclusion of individual success criteria. Scoping
by URI to exclude sections of a site is allowed so that authors can make
claims for just some parts of a site. Example 3 above is a scoped
conformance claim. 

<end of current text>

<start proposed text to add to the end of the above>

 

Scoping can include and exclude parts of a site.  But if any Web unit
that is part of an authored unit or part of a process or does not meet
WCAG 2.0 at some conformance level then no Web unit that is part of the
authored unit or part of the process can claim conformance at that
level. 

 

Example 1:  An online store has a series of pages that are used to
select and purchase products.  All pages in the sequence must conform in
order to claim conformance for any page that is part of the  sequence.

 

Example 2:  A site has a collection of videos for which it was not
required to and did not want to claim accessibility.   The site can
locate the videos in one location (e.g. example.com/movies) and then
write a conformance claim for the site or section of the site that
excludes that location.  As long as the pages on the site only linked to
the videos (and did not embed them in a Web page or other web unit) the
conformance claim would be valid.  Linking to inaccessible content does
not make a page inaccessible.  Only if that content is rendered together
with the web page (or other web unit) or if the content is itself a Web
unit within the set of URIs to which the conformance claim applies (or
if the Web unit is part of a process for which a claim is made) would it
have to meet the guidelines in order for the claim to be valid.

 

This scoping provision does not preclude an organization, customer, or
government from requiring that all parts of a site be accessible or meet
some standard including WCAG.  WCAG does not require that full websites
conform, although that is certainly seen as desirable.   A conformance
claim only requires conformance for Web Units that are in the URI set
described in the claim.
