NOTEelement may contain an arbitrary amount of text. Some standard markup would be useful here. The easiest solution is to adopt the XHTML DTD introduced in Chapter 20, Reading Document Type Definitions. It's not necessary to rewrite it all. Simply use a parameter reference entity to import it. We'll allow each

<!ENTITY % xhtml SYSTEM "xhtml/XHTML1-s.dtd"> %xhtml; <!ELEMENT NOTE (REFERENCE*, body)>
