The new feature is that if you define a parameter entity
called "ibtwsh.include" before incorporating IBTWSH into another
DTD, then the element or elements named there will be allowed
as part of horizontal content. This allows domain-specific
elements to be inserted into running IBTWSH text.
To include multiple elements, separate them with | characters.
Examples:
<!ENTITY % ibtwsh.include "REF">
<!-- allows REF elements in IBTWSH text -->
<!ENTITY % ibtwsh.include "REF | DEF">
<!-- allows REF or DEF elements in IBTWSH text -->
The default value of ibtwsh.include is "XML".
