It works for me.  Good solution, thanks.

There appears to be a minor typo.  I would have written "For
hierarchical 
list structures, it is recommended that user-agents announce the nesting

depth of list items." (singular "list")

I'm thinking this might belong in the preceding paragraph rather than 
specifically under disc, circle, square.  Typically, if these are
ordered 
lists, change in level may be indicated visually by changing numeric
style.  
However, if when changing levels we switch from upper-alpha to
lower-alpha, 
or from Arabic to Roman numerals, there would not be any change in how
the 
item letters or numbers are read aloud, so some indication of the
nesting
depth would still be needed.

Hope this helps,
