Eclipse Wild Web Developer Generic Editor: How to share the language server XML formatting settings within a team?

Question

So far we have used the XML Editor from the Web Tools Platform (WTP).

• It does not support save-actions for automatic formatting on save.
• It does not support project-specific formatting settings (only workspace settings)

I am now learning that the Wild Web Developer project provides an alternative editor for XML files, called "Generic Editor".

• It can be set as default in Preferences - File Associations
• It ignores the workspace XML Editor settings, and instead uses a language server (LemMinX)
• I see some language server settings in the workspace Preferences (see screenshot)

Now I have the same question as with the WTP Editor:

Are there any project specific configuration files that we can put under version control to ensure that every team member automatically uses the same formatting settings for each project?
