 If I look at the XML conformance tests, I can find the test with the ID ibm-valid-P65-ibm65v02.xml has the below external DTD <?xml version="1.0" encoding='UTF-8'?> <!--dtd for production 65--> <![IGNORE[ this is some stringwithout brackets <![ <!ELEMENT animal EMPTY> ]]> this is another string without brackets ]]> <!--Positive test. Pattern2--> This is in line with the spec, which has the below definition [61] conditionalSect ::= includeSect | ignoreSect [62] includeSect ::= '<![' S? 'INCLUDE' S? '[' extSubsetDecl ']]>' [VC: Proper Conditional Section/PE Nesting] [63] ignoreSect ::= '<![' S? 'IGNORE' S? '[' ignoreSectContents* ']]>' [VC: Proper Conditional Section/PE Nesting] [64] ignoreSectContents ::= Ignore ('<![' ignoreSectContents ']]>' Ignore)* [65] Ignore ::= Char* - (Char* ('<![' | ']]>') Char*) "Validity constraint: Proper Conditional Section/PE Nesting If any of the "<![", "[", or "]]>" of a conditional section is contained in the replacement text for a parameter-entity reference, all of them MUST be contained in the same replacement text." My question is: Why is the ignore section not expected to be valid declarations like an <![INCLUDE[]]> section? I mean, if you have to check the IgnoreSection of a DTD anyway to ensure that the <![ and ]]> are all correct, it seems a bit of a waste to have to implement dedicated parsing rules for something you are going to be discarding regardless. Is this a holdover from SGML? Or was there some other motiviation? Just curiosity really; would be interested to learn more about XMLs history. Thanks in advance, Regards, Daniel
