Hi Shadi,

Thanks for the quick response!

Does that mean the following?

1) A web developer codes a website
2) There are incorrect nested elements in his code
2) He picks Technique number 4, the one I mentioned, which is a combination of H74, H93, H94.
3) Because the technique doesn't address the nested elements-issue, his website will pass the Success Criterion.

There is also H75: Ensuring that Web pages are well-formed
- https://www.w3.org/TR/WCAG20-TECHS/H75.html

Also G134 and G192 can be used for full validation of web content.

I found this by using the "How to Meet WCAG 2.0" quick reference guide:
