indefinite loop in Xerces ?

[Etienne Roy <er...@us.ibm.com>]

Hi all,

I've been having problem validating instances against a schema, and
basically the problem comes from importing schemas.
Simplifying, the core problem is :
I have two namespaces, each one with it's schema and each one importing the
other. Xerces just loop and crashes creating validator.
AFAIK, the recursive inclusion of the schemas is allowed by the spec. The
definitions are not recursive, it's just
that the namespaces need definitions included in each other.

Is it a known issue in Xerces ?

Thanks for any help.

PS: more specific information:

using xerces 1.3.1 w/  java version "1.3.0"
testing w/ sax.SAXCount -v

test schemas:

<schema xmlns="http://www.w3.org/2000/10/XMLSchema"
        xmlns:first="http://www.first.test"
        xmlns:second="http://www.second.test"
        targetNamespace="http://www.first.test"
        elementFormDefault="qualified">

    <!-- import the second namespace -->
    <import namespace="http://www.second.test" schemaLocation="loop2.xsd"/>

  <element name="test" type="string"/>

</schema>

and

<schema xmlns="http://www.w3.org/2000/10/XMLSchema"
        xmlns:first="http://www.first.test"
        xmlns:second="http://www.second.test"
        targetNamespace="http://www.second.test"
        elementFormDefault="qualified">

    <!-- import the first namespace -->
    <import namespace="http://www.first.test" schemaLocation="loop1.xsd"/>

  <element name="unused" type="string"/>

</schema>

and test instance:

<?xml version="1.0" encoding="UTF-8"?>
<test xmlns="http://www.first.test"
      xsi:schemaLocation="http://www.first.test loop1.xsd"
      xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"/>

Regards.
