In testing the output from QDoc with the comments file feature, it appears the inherited by list is dropped for qml types, e.g.

-<p>The following members are inherited from <a href="qml-qtquick-controls2-itemdelegate.html">ItemDeleg ate</a>.</p> -<ul> -<li class="fn"><b><b><a href="qml-qtquick-controls2-itemdelegate.html#highlighted-prop">highlighted</a> </b></b> : bool</li> -</ul> -<p>The following members are inherited from <a href="qml-qtquick-controls2-abstractbutton.html">Abstrac tButton</a>.</p> -<ul> -<li class="fn"><b><b><a href="qml-qtquick-controls2-abstractbutton.html#action-prop">action</a></b></b> : Action</li>
