Mavlink message generation error

[weiyuhe]

I am trying to follow the procedure on: https://docs.px4.io/master/en/ros/mavros_custom_messages.html
Using mavlink-generator, here are the procedure that I followed:

    For XML, "Browse" to /PX4-Autopilot/mavlink/include/mavlink/v2.0/message_definitions/standard.xml.
    For Out, "Browse" to /PX4-Autopilot/mavlink/include/mavlink/v2.0/.
    Select Language C
    Select Protocol 2.0
    Check Validate

But I am getting the following error:
ERROR:SCHEMASV:SCHEMAV_CVC_COMPLEX_TYPE_3_2_1: Element 'field', attribute 'instance': The attribute 'instance' is not allowed.

This is a duplicate of ArduPilot/pymavlink#243
Looks like I will need to fix that at some point. But this is a duplicate so closing this.
