Problem: 1. I want to define an abstract element <_Observation>, whose substitutionGroup includes elements such as <Quantity> which has simple content of type xsd:double <Value> with simple content of type xsd:string <Count> with simple content of type xsd:nonNegativeInteger e.g. Can I define an abstract base type with no content (complexType?), or of "anyType" (can this be a simpleType?), and then "restrict" the base to the various simpleTypes? 2. Can I also derive e.g. <TwoQuantity> with complex content - a sequence of <Quantity> elements - by extension from the same base <_Observation> type? e.g. Is it possible to extend a simpleType by inserting elements as a content model? I've a feeling that the second case is easier than the first, but have been going round in circles on this and need some help! -- Simon.Cox@dem.csiro.au CSIRO Exploration & Mining T:+61(8) 9284 8443 F:+61(8) 9389 1906 M:0403 302 672 http://www.ned.dem.csiro.au/research/visualisation/
