If I'm reading the code correctly, this feature affects two gfsh commands, create region and describe region. It will impact the user guide, at minimum, in the descriptions of those two commands, and possible in a gfsh usage section. Please address these documentation tasks -- if not in this JIRA/PR pair, then in a separate JIRA/PR pair. Thank you.
