Do you remember why we had local > global in the past? And can you make a good call for global > local? I'm happy to merge this, we just want to ensure we know why this is a good direction.

I don't really know. I guess it's so the user can get the most context: a syntax error is more specific than just "not valid"

And can you make a good call for global > local?

I vouch for this because you can still get the syntax error by hovering the highlighted area.

Thanks. Makes sense to me, along with prior discussions in camunda/camunda-modeler#3845 (comment) and following.

If there is a global (in the larger context) error provided, we'll always show that over the local error.

Thinking about it global should rather be called externally provided to make that clear. Not required for this fix though.
