The gnue-forms.dtd (forms/doc/gnue-forms.dtd) has several
well-formedness problems. I realize it is a generated file, but I
don't realize what .gfd it's generated *from*, and I'm not about to
fiddle with gnuedtd without knowing what to check it against :)
- Comments along the lines of
<!-- +-------------------+ -->
<!-- | Hello, World! | -->
<!-- +-------------------+ -->
XML 1.0 spec (2nd ed), section 2.5 (Comments), 1st paragraph, says
[...] For compatibility, the string "--" (double-hyphen) must
not occur within comments.
The patch turns these comments into
<!-- +- - - - - - - - - -+ -->
<!-- | Hello, World! | -->
<!-- +- - - - - - - - - -+ -->
- Several AttListDecls are broken, because AttListDecls are
AttlistDecl ::= '<!ATTLIST' S Name AttDef* S? '>'
AttDef ::= S Name S AttType S DefaultDecl
DefaultDecl ::= '#REQUIRED' | '#IMPLIED' | (('#FIXED' S)? AttValue)
note that '#DEFAULT' doesn't exist. You just put the default
value. This patch therefore removes all '#DEFAULT's.
- boolean parameter-entity reference is misdefined:
<!ENTITY % boolean "(%true;) #IMPLIED">
<!ENTITY % true "">
which is wrong as well as not being well-formed; you probably wanted
something along the lines of
<!ENTITY % boolean "(%true;|%false;) #IMPLIED">
<!ENTITY % true "1">
<!ENTITY % false "0">
the patch fixes this, too; the values for 'true' and 'false' are as
above, but they might be wrong (you tell me).
