The documentation for [[ https://secure.phabricator.com/conduit/method/differential.setdiffproperty/ | `differential.setdiffproperty` ]] is unclear. It should be updated by including the following information.
1. What are the allowed values for `name`?
1. For each allowed value for `name`:
1. What is the intended meaning of the property with that name?
1. What are the allowed values for `data` when this name is specified?
1. Does the property impact the UI in any way, or is it only used internally?
In addition to this basic description, one or more examples showing a complete JSON message for this API call would be very helpful.
