Need a way to skip process where isExecutable='false'

In my application I have a BPMN file that has a mix of executable and non-executable processes.
I need to make the BpmnParse class skip processing of any process that sets isExecuatble='false'
so I avoid problems during its being processed.

A proposed solution is that BpmnParse.parseProcessDefinitions() be modified to check if process/@isExecutable is set and is false.
If so, parser should skip processing that process.

Below is a simple patch that implements the proposed solution. It has passed the junit regresion test suite.
Does this seem reasonable? If so, shall I go ahead and file a JIRA RFE?

As an alternative, you can use a transformation of Activiti Cycle to extract a particular Pool from a Collaboration. The developer-friendly tab in the Cycle web frontend uses it. However, you can also use the Java libraries of the Cycle backend directly.
