I do not know what is needed.  Function org-html--build-meta-info
should return valid XHTML (also in case of HTML5, I believe that
Org syntax is preferable over ignored [1] HTML tags).

Based on the treatment of meta elements for author and description
in that function, alternatives might use org-element-interpret-data
(author) or not (description).  I do not understand the role of
org-element-interpret-data to generate author information.  Which
=E2=80=9Cnon exportable objects=E2=80=9D can be skipped by that function (as
mentioned in a comment in org-html--build-meta-info)?  Should they
also be skipped for description or title?

Best wishes
Jens
