Stringifier support

[dontcallmedom]

respec doesn't support stringifier in the following WebIDL fragments:
interface foo {
stringifier attribute DOMString bar;
};
(that one seems to prevent further WebIDL processing?)

interface foo {
stringifier DOMString ();
}
(this one is shown as if DOMString was the name of the method, and stringifier its type)

[dirkschulze]

As a note,

stringifier;

is possible as well and equivalent to:

stringifier DOMString ();

This is being handled by the new WebIDL module.
