Add class directives for ``xml.dom`` by AA-Turner · Pull Request #138419 · python/cpython

User should not see class Element here, nor the entry "Element (xml.dom class)", because xml.dom.Element does not exist.

It would be nice to make some class references referring to corresponding section in this file, for example, :class:`Document` in the xml.dom.minidom.parse() description to Document Objects. But not for all (for example NodeList does not exist, it is just a list). Sphinx is bad in using nested markup, so we cannot make a link from Document formatted as class to arbitrary anchor. Can we? If this is possible, it would be an ideal variant -- make all class references inert and add links manually.

Before we find a satisfying solution, it is better to leave unresolved references as a reminder.
