HTML: is it possible to provide an alternate document title?
You can't use

<title>. See ARIA in HTML:
According to MDN the
<title> element supports only global attributes (they include
aria-* attributes) but I think it is not supported by most screen readers.
Accessibility inspector viewing page with this (see below)
<title> element in Firefox shows “a” in the document name field so Firefox does not support alternate document titles.
… <title alt="b" aria-label="c">a</title> …
