revisionId property
The revision ID of the form.
Used in the WriteControl in update requests to identify the revision on which the changes are based. The format of the revision ID may change over time, so it should be treated opaquely. A returned revision ID is only guaranteed to be valid for 24 hours after it has been returned and cannot be shared across users. If the revision ID is unchanged between calls, then the form has not changed. Conversely, a changed ID (for the same form and user) usually means the form has been updated; however, a changed ID can also be due to internal factors such as ID format changes.
Output only.
