Bpmn.io Diagram export and import into Camunda Modeler 7.3 Namespace issue

The exported .bpmn-File from bpmn.io v 12.1 works fine in camunda. The Class Definition of a ServiceTask which I specified via the properties Panel is not recogniced by camunda. A PropertyPanel related thread is here: Extending the Properties-Panel for ServiceTasks (Input variable mapping)

The exported file from bpmn.io:

<?xml version="1.0" encoding="UTF-8"?>
<bpmn2:definitions 
xmlns:bpmn2="http://www.omg.org/spec/BPMN/20100524/MODEL"
 xmlns:camunda="http://camunda.org/schema/1.0/bpmn"

  </bpmn2:process>
  <bpmndi:BPMNDiagram id="BPMNDiagram_1">
    <bpmndi:BPMNPlane id="BPMNPlane_1" bpmnElement="Process_1">
      <bpmndi:BPMNShape id="ServiceTask_1t3yyks_di" bpmnElement="ServiceTask_1t3yyks">
        <dc:Bounds x="536" y="205" width="100" height="80" />
      </bpmndi:BPMNShape>
    </bpmndi:BPMNPlane>
  </bpmndi:BPMNDiagram>
</bpmn2:definitions>

vs. a exported file from camunda itself:

<?xml version="1.0" encoding="UTF-8"?>
<bpmn2:definitions 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:bpmn2="http://www.omg.org/spec/BPMN/20100524/MODEL"
 xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI"
 xmlns:camunda="http://activiti.org/bpmn"
 xmlns:dc="http://www.omg.org/spec/DD/20100524/DC"
 xsi:schemaLocation="http://www.omg.org/spec/BPMN/20100524/MODEL BPMN20.xsd"
 id="_yqbMYJKrEeWJxMhuO2Z5Mg"
 exporter="camunda modeler"
 exporterVersion="2.7.0"
 targetNamespace="http://activiti.org/bpmn">
 
  <bpmn2:process id="Process_1" isExecutable="true">
    <bpmn2:serviceTask id="ServiceTask_1" camunda:class="xx.yy.ee.dd.CC"/>
  </bpmn2:process>
  <bpmndi:BPMNDiagram id="BPMNDiagram_1">
    <bpmndi:BPMNPlane id="BPMNPlane_1" bpmnElement="Process_1">
      <bpmndi:BPMNShape id="_BPMNShape_ServiceTask_3" bpmnElement="ServiceTask_1">
        <dc:Bounds height="80.0" width="100.0" x="132.0" y="139.0"/>
      </bpmndi:BPMNShape>
    </bpmndi:BPMNPlane>
  </bpmndi:BPMNDiagram>
</bpmn2:definitions>

The xmlns:camunda Namespace is a different one. Is this behavior correct because of the targetNamespace="http://activiti.org/bpmn" definition and therefore I need a conversion/import? Or is this behavior not expected?

Camunda will change its namespace from http://activiti.org/bpmn to http://camunda.org/schema/1.0/bpmn with the upcoming Camunda BPM 7.4 release (it will still support the old namespace though).

To be future-proof we chose the camunda namespace as the one used in our properties panel.

As an unfortunate side-effect the bpmn.io modeler + properties-panel will not support the activity namespace unless you patch that support into it yourself.

Applications built around bpmn.io will need to come with a migration path from activity to camunda.

Where can I find the XSD Schema File for the namespace http://camunda.org/schema/1.0/bpmn?

I have not had any luck searching for it myself neither via google nor on github nor in the provided .jars.

Thanks for pointing me in the right direction!
