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.
