Ah, that's exactly what I was looking for.
Two things - 1, I missed it in the docs, in part because it's only listed in the includelet list as "my-references" with no description. Could the {{available-includelets}} feature include the documentation summary about the available items, and/or links to the specific docs on them?
2 - the page references don't get updated when a page is first created. That is, if I include a link to a non-existent page on "Foo_Page" it gets rendered in red as expected on that page; if I click on the red link I get taken to a form to create that page, as expected, and then I go back to Foo_Page the link is now active; however the reference does not exist until I edit and re-save Foo_Page again. This has the effect of the easiest way to create new pages leading to apparently orphaned pages.
