ERN message without resources

An ERN feed containing a NewReleaseMessage but no Resource file is valid. 

In most situations, a DSP should receive binaries with the initial NewReleaseMessage but, especially when communicating pre-order Releases, this may not always be the case.

DSPs must, however, be in receipt of all binaries on “street date” of a Release. In order to signal that a DSP is missing binaries it may wish to use the ErnAcknowledgementStatusMessage defined in the FTP choreography for Release deliveries to signal to the label that it is missing binaries:

<ReleaseStatus>
  […]
  <ReleaseStatus Namespace=”…”UserDefinedValue=”ResouceBinariesMissing”>
    UserDefined
  <ReleaseStatus>
  […]
</ReleaseStatus>

Users of the web service choreography can use the POST ReleaseStatus method to post an ErnAcknowledgementStatusMessage as per above.
