> As evidenced in numerous pull requests, developers are often unaware of the
> behavior of {{PropertyDescriptor}} {{name}} and {{displayName}} attributes.
> Originally, {{name}} existed and served as both the UI display value for the
> processor properties configuration dialog and as the unique identifier when
> writing/reading the properties from file storage. However, a change to the
> {{name}} value after the flow had been persisted could cause issues
> retrieving the value from file storage. Thus, {{displayName}} was introduced
> as the UI display value to allow for backward-compatible updates. The
> documentation does not sufficiently explain this information and can better
> encourage developers to provide both {{name}} and {{displayName}} attributes
> in order to be proactive on flow compatibility and to improve the foundation
> for internationalization and localization of the UI.
