Hi everyone,

Here is the proposed change that I alluded to at the beginning of the 
call. Basically, it makes a wording addition (and adds a new success 
criteria ) to a Priority 3 checkpoint (Checkpoint 3.5).

The new success criteria requires at least one mechanism for 
automatically sharing text alternatives for non-text objects and media 
equivalents for time-dependent presentations between multiple authors 
working simultaneously.

Of course I'm open to re-wordings. I just think it is an important area 
which we haven't really touched on yet and which seems to rise higher 
than being merely a technique.



--------------------
Proposed Changes to Checkpoint 3.5
--------------------

3.5 Assist the author with managing, editing, reusing and sharing text 
alternatives and media equivalents. [Priority 3]

Rationale: Simplifying the initial production and later reuse of text 
alternatives (e.g. long text descriptions) and media equivalents (e.g. 
captions for video) will encourage authors to use them more frequently.

Techniques: Implementation Techniques for Checkpoint 3.5, Evaluation 
Techniques for Checkpoint 3.5

Success Criteria:

- When a text alternative for a non-text object is added, the tool must 
record this event in a way that allows the text alternative to be 
offered to the author for modification and re-use if that non-text 
object is re-used.

- When a media equivalent for a time-dependent presentation is added, 
the tool must record this event in a way that allows the media 
equivalent to be offered to the author for modification and re-use if 
that time-dependent presentation is re-used.

- The tool must support at least one mechanism for automatically sharing 
text alternatives for non-text objects and media equivalents for 
time-dependent presentations between multiple authors working 
simultaneously.



--------------------
Existing Checkpoint 3.5
--------------------

3.5 Provide functionality for managing, editing, and reusing alternative 
equivalents. [Priority 3]

Rationale: Simplifying the initial production and later reuse of 
alternative equivalents will encourage authors to use them more 
frequently. In addition, such an alternative equivalent management 
system will facilitate meeting the requirements of Checkpoint 3.4.

Techniques: Implementation Techniques for Checkpoint 3.5, Evaluation 
Techniques for Checkpoint 3.5

Success Criteria:

- When non-text objects have been previously inserted using the tool, 
the tool must suggest any previously authored textual equivalents for 
that non-text object.
