Issue 556 and 669

Dear Gang,

After a lot of dicussion between Wendy, Matt May and myself here is a proposal 
for changes to the level one success criteria for guideline 1.3. [1]

Bugs 556 [2] and 669 [3] are associated with these changes.

The proposal splits success criteria one into two, and removes the 
differentiation of hierarchical and non-hierarchical relationships. This 
gives the first two sucess criteria of guideline 1.3 as:

1. "Structures and relationships of the content can be derived 
programmatically (for example, through a markup or data model)"

2. "Differentitation of content to imply additional meaning or stress, such as 
the types of emphasis commonly denoted by bold or italics, can be dervived 
programmatically."

The current sucess criteria two would also become success criteria three. 
There is an issue with the words "imply additional meaning" and testibility.


While exploring this issue we discovered issues surrounding some technologies 
and their ability to natively denote semantic types such as paragraphs, 
headers and lists. SVG for example appears to have no semantic elements, 
although Wendy is talking to Dean from the SVG group about ways to proceed 
with techniques for SVG in this area. There is a lot to look at with this 
issue for the techniques taskforce.
