This object is used to optionally associate an id with
a license checkin/checkout request for the feature name
specified in the 'clmLicenseRequestFeatureName' object.
The application can choose to set a meaningful name for
this object. If 2 requests have the same value for appName
then they are treated as same requests. If this object is
not set or contains zero length string then each
checkin/checkout request is treated as a distinct request.
