Two questions:
1) Inside my custom language, I'd like to support Class Name completion (for
custom language elements that refer to java classes in the current project).
Is there any infrastructure/support to help with this?

2) If (1) is possible (perhaps this is where that CompletionData stuff comes
in?), will it still work when I embed my language (say inside an XML attribute).
The reason I ask this is because default XML editor already has classname
completion inside attribute values, and when I inject I want to override
this (make it more specific).

Basic support for this is incredibly easy to get: Make your attribute's type PsiClass.
You can also easily restrict the allowed classes to a certain super class/interface:

 getExceptionClass();
