I've done some research about how "avoid deprecated features" is 
interpreted by validation services for WCAG 1.0, Guideline 11.2 with the 
following results.

1. AccMonitor by HiSoftware as used on Cynthia Says will apparently not 
pass any deprecated elements or attributes. This means only strict HTML 
will pass Prioirty 2.
2. The Bobby validation test will not pass any deprecated elements of HTML 
4.0. The Bobby test ignores deprecated attributes. This is clearly 
indicated in their help documentation.
3. A-Prompt from the University of Toronto apparently ignores 11.2.

How does a Web Site indicate to a validation service and the public that a 
web page is using markup "violated for backward compatibility"? The word 
"avoid" allows for human interpretation that does not work for software. 
When you say "avoid deprecated features" do you mean "avoid deprecated 
elements" or "avoid deprecated elements and attributes"?

In the book "Accessible Web Sites" Cynthia Waddell indicates that countries 
are starting to use the WCAG as a part of their laws. This places an 
awesome responsibility on the WAI to avoid ambiguous meanings. Can the WAI 
provide a Validation test to avoid the different interpretations that 
currently exist? If not maybe you could change "avoid" to "minimize the use 
of deprecated features" or "minimize the use of deprecated elements and 
attributes." This would clearly signal that human judgement is involved 
instead of the absolute test that Validation software imposes. Another 
alternative would be simply leave 4.1d off and just let 4.1a carry the burden.

Good Luck on working out WCAG 2.0.
