I'm writing a plugin to support NHibernate mapping files. I deferred
building PSI for the mapping file until 4.0 EAP because Sergey said that
xml support will be improved in 4.0.
Anyway I'm looking into support for renaming a property or field which
is mapped. Can you give me some hints what I must do to get my plugin
called if a C# symbol is renamed? Will these mechanics change in 4.0?
