For example <!NOTATION base64 SYSTEM "http://www.somewhere.com/base64-decoder.applet"> <!ELEMENT BINARY ( #PCDATA )> <!ATTLIST BINARY encoding NOTATION ( base64 ) "base64" > ... <BINARY>...</BINARY> An element can have one NOTATION attribute, which specifies how to interpret the element's data. Often this is used to restrict possible notations to lists of types, for example <!ATTLIST figure type NOTATION ( gif | epsi | cgm | jpeg ) #REQUIRED > Developers of generic XML tools should make sure that their systems provide ways to interpret NOTATION attributes appropriately: it is a mechnism like MIME media-types, but may be on a finer grain. It is not a mechanism for multi-part documents (unless the DTD is a DTD for representing multipart documents of course) because the notation processor (which the SYSTEM identifier on the NOTATION declaration would identify) runs after the XML processor.
