Comment Type: technical
Summary of Issue: meaningful and logical sequence
Comment (Including rationale for any proposed change):
The actual wording of this Criterion appears to relate only to the need for a \"correct reading sequence\" to be programmatically determined. No definition is provided for what is meant by \"correct reading sequence\" and the Understanding SC 1.3.2 document appears to be primarily concerned with ensuring assistive technologies do not distort the presentation of material in such a way as to confuse the users of these technologies. 

I feel that it is also important for material to be presented in a logical and clear way, particularly for people with cognitive and learning disabilities. Of course, I recognise it is not possible to determine if something is \"logical\" with a machine; however I believe it is very possible for human testers to reliably determine when the sequence of content or information is not meaningful or logical. 

SC 1.3.2 should be rewritten so that it is also able to provide some assistance to people with cognitive limitation, see following example; 

Proposed Change:
1.3.2 Meaningful Sequence: When the sequence in which content is presented affects its meaning, the reading order of the material is logical and a correct reading sequence can be programmatically determined. (Level A)
