I took an ACTION [1] to reword section 3.5 Content navigation by content
structure [2] of the Media Accessibility User Requirements document to avoid use
of the word "DOM" as a synonym for "hierarchical" or "structural."  I propose
the following text:

This is, of course, a hierarchical view of content. However, effective
navigation of a multi-level hierarchy will require an additional control not
typically available using current media players. This mechanism, which we are
calling a "granularity-level control," will allow the user to adjust the level
of granularity applied to "next" and "previous" controls. This is necessary
because next and previous are too cumbersome if accessing every node in a
complex hierarchy, but unsatisfactorily broad and coarse if set to only the top
level of the hierarchy. Allowing the user to adjust the granularity level that
next and previous apply to has proven very effective—hence the adjustable
granularity level control.

For your reference, the existing text is as follows:

This is, of course, a DOM view of content. However, effective DOM-based
navigation will require an additional control not typically available on current
media players. This real-time control, which we are calling a "granularity-level
control," will allow the user to adjust the level of granularity applied to
"next" and "previous" controls. This is necessary because next and previous are
too cumbersome if accessing every DOM element, but unsatisfactorally broad and
coarse if set to only the top hierarchical DOM level. Allowing the user to
adjust the DOM level that next and previous go to has proven very
effective—hence the real-time granularity level control.

REgards,

Mark
