Conceptually, they are the same thing. With the type substitution the element name stays the same and the type information is supplied in the xsi:type attribute. With substitution groups, the type information is embedded in the element name. I personally think that the substitution groups approach results in a cleaner vocabulary. Consider: <person name="John Doe"/> <person xsi:type="superman" name="James 007 Bond" can-fly="false"/> <person xsi:type="batman" name="Bruce Wayne" can-fly="true" wing-span="10"/> Vs: <person name="John Doe"/> <superman name="James 007 Bond" can-fly="false"/> <batman name="Bruce Wayne" can-fly="true" wing-span="10"/> Boris -- Boris Kolpackov, Code Synthesis Tools http://codesynthesis.com/~boris/blog Open source XML data binding for C++: http://codesynthesis.com/products/xsd Mobile/embedded validating XML parsing: http://codesynthesis.com/products/xsde
