Publishing with Org mode version 9.3.6 (release_9.3.6-419-gd9b1fb) I get
an validation error using http://validator.w3.org/check. The error is:
----- Begin -----
Warning Line 205, Column 74:
cannot generate system identifier for general entity "dn"
…rn:btih:1f739d935676111cfff4b4693e3816e664797050&dn=gpl-3.0.txt GPL-v3-or-Later
An entity reference was found in the document, but there is no
reference by that name defined. Often this is caused by misspelling
the reference name, unencoded ampersands, or by leaving off the
trailing semicolon (;). The most common cause of this error is
unencoded ampersands in URLs as described by the WDG in "Ampersands
in URLs".

The cause is ox-html, which has the following lines
./lisp/ox-html.el:235:// @license

I think the culprit is commit 68fa5e589f00c8d5b4f7f0dc70be6ebe59238bb8,
11 Feb.
Is it possible to fix this?
