That's right, in HTML5. It's a bug in the validator that it says 
otherwise, see
The unstable development version of the validator,
has this bug fixed (and your document validates in it).

This may, in part, reflect the nature of HTML5 validator as experimental 
software that checks against some "specification" which is not 
identified in public and which may change at any moment without notice 
and often does.

Not unless you make mistakes. But it's really not necessary to use &amp;

Well, here we have yet another reason for not using such plates; for 
other reasons, see

The point is that your document is (right now at least) valid as per 
HTML5 CR. But if you put the "Valid HTML5" plate there the usual way, it 
is a link to the validator, so if anyone clicks on it, he will now get 
error messages and may incorrectly regard you as a liar!
