It appears that this change was introduced in commit
d5bbf365533ba45d72ebed8121c7612c860ea944. It also introduced the
insertion of the attribute "data-editor-type" in the HTML export, when
1. `org-html-klipsify-src' is true, and
2. an HTML source block is being exported.
Now, "data-editor-type" is not a valid attribute with respect to the
XHTML1 Strict DTD (or any other W3C X/HTML DTD). Therefore, when 1 and
2 are true, this attribute renders the exported HTML files invalid with
respect to the DTDs in `org-html-doctype-alist'. I think this would
count as a drawback to those who care about HTML validation, especially
since ox-html indicates its concern for validation through
`org-html-validation-link', etc.
I don't know what is the best way to deal with this problem. One
possibility is to put a warning in the documentation of
`org-html-klipsify-src' that setting it to true would lead to invalid
HTML exports when the Org file contains an HTML source block.
Cheers,
Raghu.
