Is it possible to remove isc_dataFormat from the request (RestDataSource)

[wallytax]

When data is fetched from a DataSource class as defined below...

isc.defineClass('CustomersDataSource', isc.RestDataSource);
CustomersDataSource.addProperties({
    dataFormat: 'json',

    dataURL: '/customers',

    operationBindings: [
      { operationType: 'fetch', dataProtocol: 'getParams' },
      { operationType: 'add', dataProtocol: 'postParams' },
      { operationType: 'update', dataProtocol: 'postParams', requestProperties: { httpMethod: 'PUT' } },
      { operationType: 'remove', dataProtocol: 'postParams', requestProperties: { httpMethod: 'DELETE' } }
    ],

    sendMetaData: false,

    transformRequest: function (request) {
      if (request.operationType === 'fetch') {
        request.params = isc.addProperties({}, request.params, {
          offset: request.startRow,
          limit: request.endRow - request.startRow
        });
      } else {
        request.params = isc.addProperties({}, request.params, {
          authenticity_token: Backend.getProperties().authenticity_token
        });
      }
      return this.Super('transformRequest', arguments);
    }
});

The request that is done, is something like:

/customers?offset=0&limit=38&isc_dataFormat=json

Is it possible to get the isc_dataFormat parameter removed?

[Isomorphic]

After calling Super(), remove it from request.params.
