DTDs and XML Editors/Parsers

Hi everyone

I've been trying out an XML editor called XML Spy (see
http://www.icon-is.com - products - software - XML Spy).  It
looks really useful so far, but I've run into a problem regarding
how it handles DTDs.

When validating an XML document on gutbook1.dtd, it throws up
some apparent errors in bookfrag.dtd which I understand is caused
by the software expanding entities prematurely.  For example, the
bookfrag DTD has:

<!ENTITY % inline.class "|quote|...etc

and later, lists in the form of:

(#PCDATA %inline.class;)

and:

(#PCDATA|title|subtitle|author|para|poem|song %inline.class;)

In order to validate XML documents to this DTD, the XML Spy
editor requires these to be:

<!ENTITY % inline.class "quote|...etc

and then:

(#PCDATA|%inline.class;)

and:

(#PCDATA|title|subtitle|author|para|poem|song|%inline.class;)

Is this something anyone else has come across, perhaps in other
software?  And should we construct DTDs in such a way as to work
with the software out there?  Or should the fact that the DTD is
technically correct be sufficient?

I'd be interested to know what you think.

Thanks,
Donna
