           Summary: Exception message contruction
           Product: WebAppsWG
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: WebIDL

I might have screwed something up, but implementing the algorithm can result in
message becoming "undefined", from this line: 

Test case:
var test = new FooError() 

function(arg0) {
  //.... arg0 is undefined. 
  //If n > 0, then:
   if (arguments.length > 0) {

  //Let S be the result of calling ToString(arg0).
  var S = ECMAScript.ToString(arg0);

Maybe the spec should check that arg0 is not undefined? 

Question: can a default message be set somehow in through the IDL?
