xml module: Make user interface much more restricted (#28657)
So the xml module has a lot of parameters that combined together do specific things. however it does not really describe which parameters are required together, or which ones are required. This PR fixes that situation and makes it impossible to provide confussing parameters combinations. Also, `pretty_print` was used as a flag to modify the output, but also as an action to reformat the file (without other change). This is problematic the way it was designed. This fixes that too. This fixes #28194
