Re: WCAG formalization (rewriting WCAG HTML techniques as automatable rules)

I have seen some new formalizable rules at [3] that I had never thought 
about, which are also very easy to rewrite. :-)

For example:

"A Positive":
Alt text is the same as src attribute

Could be rewritten as
//img[@alt = @src]

So, yes: I AM INTERESTED :-)

What should I do? I am a newbie at this mailing list (just subscribed 
since yesterday).

I would also be happy if the new WCAG could include some other formalized 
rules that I thought (but they are not really included in the original 
WCAG). For example, the "uniqueness" of acronyms and abbreviations at [4] 
is an already formalized rule, it avoids confusion to users, but it is not 
addressed in any document from WAI. Some people at the other mailing list 
(w3c-wai-ig@w3.org) have said (it is not from WCAG), but I would be 
happy if it is considered to be included.

P.S.: I will have a closer look at your references.

Cheers.
