Yes, an IDE neutral "standard" would be wonderful. Given the momentum of Padre at the moment, hope the lower layers of it will be fully reusable across other editors.

Regarding exporting, I think that just declaring method names would be too limited for some uses.

For instance, for refactorings (let's say "Rename Attribute"), the refactoring code needs to know not just the name, but which part of the source tree specifies the name.
