Thanks to Sean and Nicholas for their comments and suggestions!

FWIW, I found a couple of articles that seem pretty relevant to this task.
Unfortunately, both of them are a bit dated.  Has the web browser or screen
reader environment changed in any way that I should take into account?

  Using ARIA trees (W3C wiki, 2012)

  (Not so) Simple ARIA Tree Views and Screen Readers (Jason Kiss, 2013)

The second article suggests a "best approach" that handles some issues
that the author found in various browsers and screen readers:

  In this proposed best approach, the tree view uses an unordered list, and
  each list item has a nested link.  The list items have role="treeitem",
  and implement aria-selected, aria-level, and aria-expanded if they have
  children.  The nested link in each list item is set with role="presentation"
  and tabindex="-1".  All of these attributes are added using JavaScript,
  since the functionality of the tree view depends on scripted arrow key

Does this seem like a reasonable starting point?
