I'm trying to write a plugin that will complete an href attribute in an xml with a valid file name. I've been reading the available documentation and searched in this forum. Found this post http://intellij.net/forums/thread.jspa?messageID=5157247� really helpful except for the fact that apparently in Selena the classes ReferenceProvidersRegistry and PsiReferenceProvider are not longer where they use to be, and I can't find them.
I need to do this plugin for EAP because I need one of the fixes that were made lately so that it can recognize my DITA dtd.
Thanks in advance for any tip you can provide me!
