Having made one too many mistakes when editing app_info I decided to make a schema for it so I can at least do some basic checks.

It's far from canonical. All I can say is it works with an app_info built with aistub files. It expresses a some constraints that I assumed are true.

Anyone who might find it useful can find it here.

I use it with notepad++ and the XML Tools plugin. If anyone tries to use it, remember that schemas impose a tag order. I used the tag order that always exists in the aistub files.

If I get any feedback I can tune it.
