CSW TransactionResponse returns bad data

[etj]

Describe the bug

The identifier element in /csw:TransactionResponse/csw:InsertResult/csw:BriefRecord is missing the dc ("http://purl.org/dc/elements/1.1/") namespace.
Furthermore, the other expected elements required in csw:BriefRecord are missing.

To Reproduce

1. Perform a Transaction Insert operation
2. You'll get a result like this:

<csw:TransactionResponse xmlns:csw="http://www.opengis.net/cat/csw/2.0.2">
   <csw:TransactionSummary>
      <csw:totalInserted>1</csw:totalInserted>
      <csw:totalUpdated>0</csw:totalUpdated>
      <csw:totalDeleted>0</csw:totalDeleted>
  </csw:TransactionSummary>
  <csw:InsertResult handleRef="handleRefValue">
      <csw:BriefRecord>
         <identifier>C3B4172C-E280-0001-4B22-1B911020BEB0</identifier>
      </csw:BriefRecord>
  </csw:InsertResult>
</csw:TransactionResponse>

Expected behavior
The csw:BriefRecord should contain

<csw:BriefRecord>
   <dc:identifier>C3B4172C-E280-0001-4B22-1B911020BEB0</identifier>
   <dc:title>Sample title</dc:title>
   ...other BriefRecord elements...
</csw:BriefRecord>
