The ':' character, hexadecimal value 0x3A, cannot be included in a name

Hey Team,
I’m using a custom descriptor in order to extend the Task element and add a new attribut called RankOrder it’s working fine and the bpmn xml is well generated.

{
  "name": "customDescriptor",
  "uri": "http://customDescriptor",
  "prefix": "custdesc",
  "xml": {
    "tagAlias": "lowerCase"
  },
  "associations": [],
  "types": [
    {
      "name": "RankOrder",
      "extends": [ "bpmn:Task" ],
      "properties": [
        {
          "name": "rankorder",
          "isAttr": true,
          "type": "String"
        }
      ]
    }
  ]
}

My issue here, the new attribut is displayed as below with colon (custdesc:rankorder), which poses a problem when trying to parse the xml in the backend (based on .Net) it seems that the “:” is allowed only for the node element and not for its attribute names (Xml specification).
<bpmn:task id="Task_0ne4plj" name="In Progress" custdesc:rankorder="1">

and i get this exception:
The ':' character, hexadecimal value 0x3A, cannot be included in a name

is there any indication how to generate the attribut without colon as below:

<bpmn:task id="Task_0ne4plj" name="In Progress" rankorder="1">

thanks and regards,

Did you check your document against an online XML validator?

I don’t know about the specifics of .Net but prefixing attributes with a namespace is definitely valid XML.

The document was validated with no errors, but i could not parse it in the backend.

thank you

The fact that you could not parse it indicates an issue on the back-end side of things.

I recommend you to investigate this, rather than trying to find a workaround via the toolkit.

Looking at the XML, the prefix might be wrong, too.

You got both customdesc and customdesc_1 in the BPMN 2.0 document. Assigning the wrong namespace may cause issues during validation in the backend.
