Restricting open borders

[Colon]

I'd like to restrict the scope of open borders treaties, so they'd only allow trade and non-combat units to cross borders. Basically the rights of passage some mods have. Can I do that with simple XML modding? I want to apply the changes on the revDCM mod files, so definitely no dll changes.
Ideally, I would also like it that combat units do can cross borders when countries have a defense pact (even without open borders) or with vassalage. Same question here: can I achieve that editing XML files? Thanks in advance.

Unfortunately not, you would have to edit and recompile the DLL to implement that.

Another option might be to find a mod that has this distinction and hope that it is implemented with XML support there, but I am not aware of any actual examples of that.

Feared as much.
