Zeus (b3_5): Unable to handle recursive DTD

Hi All,

I've been using Zeus for about 6 months now on various projects. I'm very
pleased w/ the product since it has save me tons of time :-)  However, I
have this one DTD and sample XML file that I can't process.  The DTD uses=
 a
recursive definition and it seems to cause problems w/ Zeus (b3_5).  The =
DTD
and sample XML files are at the bottom of the e-mail.

When I attempt to marshal the object, I encounter a NullPointerException.
Has anyone else encountered a similar problem?  I'm using Zeus b3_5, JDK
1.4.0, Windows NT.


Here's the stack trace.

Here's the DTD file:  "dcr.dtd"

<?xml version=3D"1.0" encoding=3D"UTF-8"?>
<!ELEMENT item (value*)>

<!ELEMENT record (item+)>
<!ATTLIST record
	dcrname CDATA #REQUIRED
	dctname CDATA #REQUIRED
	type CDATA #REQUIRED

<!ELEMENT value (#PCDATA | item)*>



Here's the sample XML file:  "sample_data.xml"

<?xml version=3D"1.0" encoding=3D"UTF-8"?>
