+If the referenced Provisioned Service exists and exposes a binding secret, the `ServiceAvailable` condition status **MUST** be set to `True`.  If the referenced Provisioned Service either does not exist, or it cannot be determined if the resource exists, the `ServiceAvailable` condition status **MUST** be set to `False` with a meaningful message.
