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?
