False Positive Plugin.xml Errors

I got that with v9 as well, see post here. Everything appears to be working allright though...

Hello Brad,

No, this is a bug in IntelliJ IDEA 9.0: http://youtrack.jetbrains.net/issue/IDEA-24930

I've attached a screenshot of my plugin.xml file.  It's showing the
applicationService and psi.referenceContributor extension points as
not valid for their location in IntelliJ 9.  If I change the SDK to be
based on 8.x, they show up fine; otherwise, they should up as invalid.
Is there something I have setup wrong in IntelliJ 9?
