@DonRichards what's the best way to test this?

[DonRichards]

@mjordan This is the docs related to this PR Islandora/islandora#856

This PR needs to go in first for this to be relevant. But basically to test this is to follow the instructions provided by the MD file against the changes made in the pull/856

@DonRichards thanks. If this needs to be reviewed by the end of the sprint, it's probably best to have someone who can commit to that timeline to review it. All of my dev/testing time is going into Workbench lately and I can't even keep to my promised timelines on that.
