[jboss-jira] [JBoss JIRA] Closed: (JBPM-426) enable jpdl schema extension via namespaces

Tom Baeyens closed JBPM-426.
----------------------------

    Fix Version/s:     (was: jBPM jPDL 3.2.2)
       Resolution: Won't Fix

going forward, we want to move to validation as part of scanning the dom tree, not with xsd schema.  it can provide some hints, but it can't do full validation.  e.g. with schema, you can't validate transition destination resolution in the presence of super states.  the conclusion is that fixing the xsd to support multiple namespaces is going to take us too much time.

when we would see namespace support as our strategic way forward, this would have to be baked into all the tooling that we provide.  if we would update the schema with namespace support as you refer to, this would be a big task for us.  and the end result is that we still would have to do our own validation while parsing the dom tree.

so therefor we opt for moving towards full validation in the process parsing.  and not depending too much on the schema validation.

> Customizing jpdl elements in a process definition via application-specific XML-elements is currently only possible outside of any schema validation. XML namespaces are the canonical way to allow for the extension of jpdl so that  configuration data of delegation classes may be defined within an application-specific namespace and associated XML schema. In particular, this would be necessary to enable customization of jpdl elements
>   - action
>   - assignment
>   - handler
>   - controller
>   - task
> Bug #JBPM-332:
> http://jira.jboss.com/jira/browse/JBPM-332
> is somewhat related to this issue. However, resolution of JBPM-332
>   - only allows for arbitrary elements to appear inside jpdl files (without schema validation)
>   - and only for customizing assignments (leaving out action, handler, controller and task).
> Implementation of this feature request would be done via a more intelligent version of an EntityResolver (defined in org.jbpm.jpdl.xml.SchemaValidationHandle) that can return application specific schemas in addition to the default one for jpdl.
