Description
Component: VSCode BPMN Editor extension
Error description
Using BPMN Editor VSCode extention (0.25.0) for designing/editing processes, when we create a (Java) Service Task by reference to our product documentation [1] using the BPMN Editor, the bpmn file for the process causes a specific parser error in maven build.
I created a reproducer for the same error as the user encountered, and attached it in this JIRA.
Also, for the steps to reproduce the error, please see (*1) below.
By following the steps, you can see 2 issues/errors below, and (2) is the error actually reported by the user.
Error (1)

(*1) Steps to reproduce
I created the following 2 projects by following the documentation [1]. On Business Central, these projects can be run normally:
- example_servicetask_1a.zip
- This contains a bpmn file (process1.bpmn) created using Business Central process designer.
- example_servicetask_1a_support.zip
- This contains a Java class which ServiceTask calls.
To reproduce the errors (1) and (2), please follow the steps in jira's "Steps to Reproduce" section.

(*4) Differences between the processes (*2) and (*3):
The issue causing error (1):
- xmlns:xsi="[http://www.w3.org/2001/XMLSchema-instance]" xmlns="[http://www.omg.org/bpmn20]"
in Line (*2-1) was modified to:
xmlns:xsi="xsi"
in Line (*3-1).
The issue causing error (2):
Lines at (*2-2) were removed in (*3), and also lines at (*2-4) were removed in (*3).
Possible root cause and notes
You can see the error (1) first after saving the bpmn file using BPMN Editor.
I think (1) is the issue reported in KOGITO-5714 Stunner - every process shows error messages during compilation.
We can avoid the error (1) by modifying the bpmn file like (*1-1), but every time we save the bpmn file, we need to modify it manually.
After avoiding the error (1) by modifying like (*1-1) manually, then you can see the error (2) in question.
Regarding (2), it looks for me like that inMessageRef and outMessageRef in bpmn2:operation are actually not used in (Java) Service Task. As far as I look at (*2), (*3), (*4), in BC process designer, however, both inMessageRef and outMessageRef remain in bpmn2:operation as dummy data so as to conform to the BPMN specification (inMessageRef must exist in bpmn2:operation). On the other hand, in BPMN Editor VSCode extension, neither inMessageRef nor outMessageRef are added in bpmn2:operation, so I am suspecting that the issue (2) is a bug in BPMN Editor VSCode extension.
Acceptance criteria
It is possible to successfully build the attached projects without failures.
See the Steps to reproduce for more details.
