Ignore the error, the HTML5 spec does not reflect implementations in
this section about ARIA.
The warning is not helpful to authors nor does it accurately describe

Lite 1.1 document:
<hgroup>
<h1>Company Name</h1>
<h2 role="presentation">Tagline</h2>
</hgroup>
Spec says:
Authors must not set the ARIA role and aria-* attributes in a manner that
conflicts with the
semantics described in the following table, except that the presentation role
may always be used.
