Docutils doctree elements wrap the sequence interface (pass-through to
Element.children). So use the same operations you would on a list.

Assume doctree[0] is the title element (use, e.g. ``index =
Element.first_child_matching_class(nodes.title)``). ``del doctree[0]``
deletes the title.

Assume doctree[1] is the subtitle element. ``del doctree[2:]`` does
what you want.
