[ https://issues.jboss.org/browse/JGRP-2022?page=com.atlassian.jira.plugin.... ] Bela Ban commented on JGRP-2022: -------------------------------- Comment from [~rvansa]: So the problem is in <xs:schema ... attributeFormDefault="qualified"/> - just use "unqualified" and it will work (+ declaring the default namespace). However, I can see that the namespaces are a bit messy: * while you 'version' the main schema file (jgroups-3.6.xsd), you don't version the namespace (it's urn:org:jgroups all the time). urn:jgroups:relay:1.0 is versioned correctly ** schema location should be also versioned properly, so that you publish that on http://www.jgroups.org/schema/jgroups-3.6.xsd * you're not consistent in the namespaces formations: urn:jgroups:relay:1.0 vs. urn:org:jgroups vs. just fork. All these should be urn:jgroups:something:version or urn:org.jgroups:something:version (note the dot in org.jgroups, no colon) Since you allow custom protocols, you should add <xs:any namespace="##other"/> to main jgroups schema. Ideally, you should adapt XMLSchemaGenerator to be reusable for custom protocols (generate their own schema). -- This message was sent by Atlassian JIRA (v6.4.11#64026)
