UPDATE: Adding the pseudo-metatag, "unpublished: true" to these documents. The tag DOESN'T DO ANYTHING at this point in time BUT there is a related Jira Story, https://myplanet.jira.com/browse/MP-727 and a related git branch/commit, https://github.com/myplanetdigital/myplanetdigital/pull/94, that can make use of the pseudo tag in the future once the functionality's been completed.
