This is the schema for AWML (Augmented World Modeling Language). It defines, how a generic nexusobject is build. It does /not/ define, which elements are allowed in which nexusobject (since XML is not capable of that). For this information, see the Nexus Standard Class Schema (nscs) unordered list of arbitrary Nexus attributes a list of reverse references. This is only a preview how reverse references could look like in the next version of AWML!
