  Construct a service network from an XML description. See docs/mlt-xml.txt.

notes: >
  If there is a service with a property "xml_retain=1" that is not the
  producer, and if it also has an "id" property; then the extra service
  is put into a properties list keyed on the id property. Then, that
  properties list is placed as a property on the returned service with
  the name "xml_retain". This lets an application retrieve additional
  deserialized services that are not the lastmost producer or anywhere in
  its graph.
