Specificity of this format: the field dc:identifier contains the record permalink and also, if applicable, the direct link to the file.
Example
<dc:identifier>https://sonar.ch/global/documents/304993</dc:identifier>
<dc:identifier>https://sonar.ch/documents/304993/files/B._Leutenegger.pdf</dc:identifier>
