Conditional Sections
Synopsis
The conditional section markup provides support for conditionally including and excluding content at parse time within an XML document’s external subset. Conditional sections are not allowed within a document’s internal subset. The following example illustrates a likely application of conditional sections:
<!ENTITY % debug 'IGNORE' > <!ENTITY % release 'INCLUDE' > <!ELEMENT addend (#PCDATA)> <!ELEMENT result (#PCDATA)> <![%debug;[ <!ELEMENT sum (addend+, result)> ]]> <![%release;[ <!ELEMENT sum (result)> ]]>
