The above is 100% correct, as were the other replies you have received.

> Yup, but I tried that (explicitly declaring HTML5)

"<!DOCTYPE html>" explicitly declares an HTML5 document.

YUI CSS is not HTML, and thus are completely irrelevant to questions
about XHTML vs. HTML5.

The W3C's markup validation service will correctly validate HTML5:

http://validator.w3.org/

To sum up: The doctype declarations in Koha's OPAC and staff client
templates are correct, and are not the cause of your errors. Not all
templates are 100% valid, but you should see few errors related to
HTML markup.
