This comment has met with consensus support within the Protocols and
Formats Working Group. Please accept this as a comment from the Group.

We would, as ever, welcome the chance to discuss this with you if it
is unclear or for any reason it does not strike the CSS Working Group
as a "just do it."

</note>

System Inheritence: CSS 3.0 had introduced the style sheet properties 
so that web applications may inherit system settings for system font 
and color changes. U. S. Public Law 508 requires that applications 
respond to system font and color changes. An example of its use is 
the system setting for high contrast.
Response to these settings is critical for persons with disabilities. 
Developers of scripted web applications need to have access to these 
settings to adapt their content in response to system settings. The 
author has no mechanism to gain access to these system settings.

Since CSS 2.1 is going back to working draft and CSS3 is not due out 
any time soon, CSS 2.1 should provide a mechanism for an author to 
automatically adapt their content in response to system font and 
color changes.
