Glad to see this being discussed as it's a topic of some confusion .   To 
me, the intent of the guideline is to avoid non-DOM functions when adding 
content to a page.  Hence, any use of document.write(), innerHTML, 
outerHTML, innerText or outerText is non-WCAG 2.0 compliant.  The 
guideline is likely to cause many Web applications/pages to to be 
non-compliant as the use of document.write() and innerHTML are pervasive.

In SCR21, the test procedure says "Examine the source code and check that 
the new content is not created using document.write(), innerHTML, 
outerHTML, innerText or outerText."

Some of the evaluation tools are flagging any use of these functions as 
non-compliant with WCAG 2.0. But I don't think this is a correct 
interpretation. It is only a failure if the intent was to use the 
technique "Using functions of the Document Object Model (DOM) to add 
content to a page". We don't have a failure technique around the use of 
document.write(), innterHTML, etc. 

Perhaps we need to add a technique that demonstrates the correct use of 
these functions.
