protected RetrieveMetadataChangesResponse getMetadataChanges(
 EntityQueryExpression entityQueryExpression,
 String clientVersionStamp,
 DeletedMetadataFilters deletedMetadataFilter)
{
 RetrieveMetadataChangesRequest retrieveMetadataChangesRequest = new RetrieveMetadataChangesRequest()
 {
  Query = entityQueryExpression,
