I don't get this at all. When has there ever been a default semantic for what element containment means (except in the case of text being marked up)? Without such a semantic, saying that any of the simple permutations is different doesn't make sense. Why not <km63000><Yangtze/><River/></km63000> or <sentence id="s1"> <subject is-a="River">Yangtze</subject> <verb>has</verb> <object> <sentence id="s2"> <subject is-a="quality">length</subject> <verb>is</subject</verb> <object> <sentence is="s3"> <subject is-a="number">63000</subject> <verb>is</verb> <object is-a="metric">kilometers</object> </sentence> </object> </sentence> </object> </sentence> where the rendering to English is s3 - "63000" is kilometers s2 - "length" is 63000 kilometers s1 - "Yangtse" River has length 63000 kilometers Cheers Rick Jelliffe ----- Original Message ----- From: "Roger L.
