Multiple Defined Elements
When you compile your DTD, you may get the message:
An element name has been declared more than once. For element name.
If you see this message, the document prolog is in error. If you know that you had a valid DTD before you added the entity declaration for Arbortext tables, it is possible that one of the elements declared in your DTD has the same name as an element declared for Arbortext tables.
If you want to use integrated table editing, change the name of the element in your DTD and leave the name of the table element unchanged.
