In org-mode, how do I remove the "Validate XHTML 1.0" message from HTML export?

Question

In org-mode 7.8, how do I remove the "Validate XHTML 1.0" message at the bottom of the page?

Its neighbours can be removed with:

#+OPTIONS: author:nil email:nil creator:nil timestamp:nil

but I can't find the equivalent for the "Validate XHTML 1.0" message.

Answer 1

One way is to change the value of the org-export-html-validation-link variable to nil:

(setq org-export-html-validation-link nil)

As of org version 8.0, use:

(setq org-html-validation-link nil)

Answer 2

I used the following line in my org file:

#+OPTIONS: html-postamble:nil

but that removes more than just the validation link. Using html-validation-link instead didn't have the expected result.
