Deployment of JavaEE5 application client fails if element "application-client" has attribute "id"

I copied the following ear file to the deploy directory of the default configuration and restarted the server: http://www.informatik.fh-wiesbaden.de/~knauf/SWTVertiefung2006/stateless/Stateless.ear
(Works fine with JBoss 4 + EJB3)

It did not deploy with this error in server.log:

application-client.xml looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<application-client id="Application-client_ID" version="5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application-client_5.xsd">
<display-name>StatelessClient</display-name>
<ejb-ref>
<ejb-ref-name>ejb/GeometricModel</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<!-- A senseless "home" item is needed, otherwises JBoss would complain...-->
<home>java.lang.Object</home>
<remote>de.fhw.swtvertiefung.knauf.stateless.GeometricModel</remote>
</ejb-ref>
</application-client>

The ID attribute is valid, "application-client_5.xsd" defines this:

<xsd:complexType name="application-clientType">
<xsd:sequence>
<xsd:group ref="javaee:descriptionGroup"/>
....

<xsd:attribute name="id" type="xsd:ID"/>
</xsd:complexType>

By the way: the ID attribute is autogenerated by Eclipse/WebToolsPlatform (the above project was converted from Java2EE 1.4).
