@arindamthokder, something strange is going on with the way this cmdlet is coded, because the TransportRules and UndifiedDlpRules parameters both have "Required: True" in the parameter YAML blocks, yet they're showing up with square brackets around them in the Syntax section, which indicates they're optional. The platyPS utility itself is picking this up. I've never seen this situation before.

Also, your note is righteous, but you can't just stick it anywhere in the article. I moved the text under the Description section.
