The following relates to Section 3.5 - Binding Attachment Model.  Can
you please clarify the following: 

If I attach a binding to an element using addBiding() (or using CSS
'-xbl-binding:'),  can I still call functions defined in an xbl:script
element from within the implementation of a binding? The 6 steps defined
in section 3.5 do not specify if xbl:script elements in bounding
documents are evaluated and made available in such situations. For
example, can I do the following: 

HTML Doc: 

<html>

<script>

                var b  = document.getElementById("myButton"); 

                b.addBinding(ui.xbl#magicButton); 

</script> 

<...>

XBL Doc (ui.xbl)

<xbl>

<script> 

                var count = 0; 

                function counterInc(){ return count++;}

<script>

<binding id="magicButton">

                <implementation> 

                ({getNumber: function(){

                                var a = counterInc (); 

                                a = a + "hhhh" + count;

                                return a;

                }, 

 xblBindingsAttached: function(e){

                                alert(this.getInstanceNumber())

}})

</implementation>

</binding>

</xbl> 

If I can do the above, then it might be good to state in section 3.5
that the script element is firstly evaluated and made available to
bindings.
