Parameter entity reference error with expat
I'm working out a small DTD by inlining it with some sample data. It uses a single internal parameter entity and refers to the entity twice in the DTD. Emacs's 'psgml' seems to validate and do all the substitutions as expected. If I run the file through expat, though, it reports the following error: illegal parameter entity reference My understanding of the spec. is that a non-validating parser does not have to expand an external entity, and I could understand that behavior being applied here, but is it truly 'illegal' to use a parameter entity reference in this fashion? Here's a snippet of problematic file: __BEGIN <?xml version="1.0" encoding="UTF-8"> <!DOCTYPE options [ <!-- the whole document --> <!ELEMENT options (head?, macro*)> <!ELEMENT head ANY> <!ELEMENT app-name (#PCDATA)> <!ELEMENT version EMPTY> <!ATTLIST version major CDATA #REQUIRED minor CDATA #REQUIRED> <!ELEMENT macro (flag|arg)+> <!ATTLIST macro id ID #REQUIRED argc CDATA "0"> <!-- shared attributes for certain macro sub-elements --> <!ENTITY % entry-atts 'name CDATA #REQUIRED presence (inc|exc) "inc"'> <!ELEMENT flag EMPTY> <!ATTLIST flag %entry-atts;> <!-- ** expat quits here ** --> <!ELEMENT arg (#PCDATA)> <!ATTLIST arg %entry-atts;> ]> <options> ... </options> __END Note that the ATTLISTs for entities 'flag' and 'arg' attempt to expand an entity called 'entry-atts', for which expat reports an error. I'd appreciate any assistance in interpreting the spec. here. Is expat doing the right thing?
