My memory is that this change was for GL 1.3 L1 SC1.

I think GL 2.4 L1 SC1 was changed to something like "Navigational
mechanisms within the content can be programmatically determined"

(the June 30 wording for 2.4 L1 SC1 says "Navigation features..."
instead of "m"mechanisms")

Subject: definition of perceivable structures

Last week we changed  2.4 L1 SC1 to  Perceivable structures within the
content can be programmatically determined.

But we did not define   Perceivable structures 

Here is a candidate definition for comment. 

perceivable structures 
    structures in the document that are reflected in the presentation
and can be used for orientation and navigation including determining
relationships between parts of the content.
