This is wrong (except on what xbl stands for).  XBL is more like dhtml 
behavior in ie or rcc in svg.  It essentially allows you to define your 
own xul tags and attach behaviors to them (constructors, methods, 
properties, event handler, etc.).  You can use javascript to implement 
your xbl bindings.  This even works in remote xul (i.e. your xbl 
extensions gets downloaded with your main xul document from a web 
server).  Unpack your toolkit.jar in your mozilla distribution, you can 
see tons of examples of this.  The "corba-like IDL" thingy mentioned is 
used in xpcom, which you can use in your xbl bindings or NOT.

I totally second the comments that we don't need any more specs.  We 
have enough spec to do rich internet applications (xul+xbl+svg+rcc).  We 
only need more and solid implementations of the specs.
