If two groups express different requirements for inheritance, then the system should support different requirements for inheritance. Should inheritance be a facility of XML, or are inheritance requirements met else where in the design. Early in this list, object-oriented ideas were discussed and rejected(? - assumption) for XML. By analogy, SGML tools do not explicitly support or express inheritance. But object-oriented databases have been created that use SGML. Where in those designs is inheritance explicitly supported?
