The quickstart wildfly-ejb-multi-server-app-one-ejb quickstart fails to validate. The reason seems to be as follows:

1) jboss-ejb3.xml imports the xmlns:ci ="urn:container-interceptors:1.0" namespace.

2) boss-ejb-container-interceptors_1_0.xsd imports jboss-ejb3-spec-2_0.xsd namespace as follows:

<xs:import namespace="http://java.sun.com/xml/ns/javaee" schemaLocation="http://www.jboss.org/j2ee/schema/jboss-ejb3-spec-2_0.xsd

3) jboss-ejb3-spec-2_0.xsd imports jboss-ejb3-2_0.xsd as follows:

<xs:import namespace="http://www.jboss.com/xml/ns/javaee" schemaLocation="jboss-ejb3-2_0.xsd"/>

The use of a relative path in step 3 breaks the eclipse validator. It would be best to use full urls that point to the actual xsd file.

This fix will most likely require:
1) Changes to jboss-ejb3-spec-2_0.xsd in whatever repository it lives in
2) Changes to jboss-ejb3-spec-2_0.xsd on http://www.jboss.org/schema/jbossas/
3) Changes to jboss-ejb3-spec-2_0.xsd inside jbosstools, which typically clones all updated files living at http://www.jboss.org/schema/jbossas/
