Hey - I found this interesting:

"blog.imixs.org/2019/03/13/bpmn-2-0-the-extension-mechansim/"

It shows an effective third party use of BPMN2.

Hi, looking to get some quick help on exception on trying to run example given on documentation link(https://download.eclipse.org/bpmn2-modeler/doc/api/core.html) using enumration type below when opening property page for task ( remove enumration the no error and rest of properties show up fine).looking to extend task for some usecase with enumration with simple way described in documentation...
<!-- This <modelExtension> extends BPMN2 Activity elements and all subclasses
(Task, UserTask, etc.) Besides the boolean "isDevice", the extension adds
a new type called "Device" which contains a "type" attribute (an enum) and
a "DeviceIdentifier" type which itself contains two attributes, a String
and an Integer. Note that a specialized <propertyTab> is needed to display/edit
these extensions (see below).
-->
<modelExtension id="org.eclipse.bpmn2.modeler.examples.dynamic.activity"
name="Activity Extension"
type="Activity">
<property name="isDevice" type="EBoolean" value="true"
label="Is Device" />
<property name="device" type="Device" label="Device Definition">
<value>
<property name="type" type="DeviceType:EEnum" value="Phone Tablet Computer Banana"
label="Device Type" />
<property name="deviceID" type="DeviceIdentifier" label="Device Details">
<value>
<property name="carrier" type="EString" value=""
label="Carrier or Service Provider" />
<property name="identifier" type="EInt" value="0"
label="Device Identifier" />
</value>
</property>
</value>
</property>
</modelExtension>

<!-- This <propertyTab> will add a new tab to the Property Sheet called "Activity
Extensions". The tab will be visible for all BPMN2 Activity objects and their
subclasses (type="org.eclipse.bpmn2.Activity") In this case, the Default
property sheet page (class="default") is sufficient to display the attributes
and elements, although we could have supplied our own Java class to handle
these extensions.
-->
<propertyTab id="org.eclipse.bpmn2.modeler.examples.dynamic.activity.tab"
afterTab="org.eclipse.bpmn2.modeler.description.tab" class="default"
features="isDevice device carrier identifier" type="org.eclipse.bpmn2.Activity"
label="Activity Extensions">
</propertyTab>
it error out with exception ..
