Is there a reason that this cannot be done? That's definitely what the spec says, based on productions 63-65. Whether it *should* say that is a question. > Also, does the specification of a conditional section basically imply that > you cannot have a ']]>' character [sequence] anywhere in an ignored section, > even if it's in a literal? > > So something like this: > > <![IGNORE[ > <!ENTITY MyEntity "The ]]> text of my entity"> > ]]> So it seems. Such an entity, BTW, can't be referenced from character data, since "]]>" is illegal there (production 14), but can be referenced from attribute values. As a result, we now have the idiosyncratic property that MyEntity can be declared as above outside a conditional section, or in an INCLUDE conditional section, whereas the declaration cannot appear as above inside an IGNORE conditional section. This point seems to me to belong to the XML Syntax WG, so I have copied this response to xml-editor@w.... > Since it actually does not look at what follows the <![ part, which is > theoretically supposed to either be INCLUDE or IGNORE or CDATA, right? CDATA is impossible within the DTD, and INCLUDE/IGNORE are impossible outside the DTD, so one cannot be inside the other. It's interesting though that you can "comment out" non-XML declarations, or indeed almost any sort of junk, using an IGNORE section: <![IGNORE[ <!USEMAP this that> <!SHORTREF putcha trash here> random floating text <EM>even looks like instance text</EM> ]]> -- John Cowan http://www.ccil.org/~cowan cowan@c...
