Are you just trying to build upon DTDs? I describe my documents using many information types to create a single document layout. You could do something like this: DTD A extends DTD B DTD A describes a car, which has an engine, wheels, and a steering wheel. DTD B describes an engine in detail. It has sprockets and thingamajigs. DTDA: <!ELEMENT car (engine, wheel+, steering_wheel)> <!ELEMENT wheel (#PCDATA)> <!ELEMENT steering_wheel (#PCDATA)> <!ENTITY % engine SYSTEM "file:B.dtd"> %engine; DTDB: <!ELEMENT engine (sprocket+, thingamajig+)> <!ELEMENT sprocket (#PCDATA)> <!ELEMENT thingamajig (#PCDATA)> I know that using Oracle and Apache parsers, XML Spy, and IE 5.5 all automatically have DTD A include DTD B. Is this what you are looking for? -Pat At 05:35 PM 1/16/2001 -0800, Seetharam Samptur wrote: >Hi, > I have a DTD question. I want to represent an object model that has >inheritance.
