In the example at the end of 3.3.6 (Overloading):

* "<f2, (DOMString, DOMString, float, float, (true, false, false, false))>," seems to have a closing parenthesis in the wrong place.
* "fase" should be "false".

In 3.4 Exceptions: "of another exception member of a constant defined on the exception" should read "or a constant", I think (not totally sure).

In 4.4.5 Attributes: "For each attribute defined on the interface whose identifier is not constructor, there must be a corresponding property on the interface prototype object, unless: the identifier of the attribute is constructor;" seems redundant (not exactly a typo, but close enough).

In 4.6 "Native objects implementing interfaces": "The interface does not have a [Constructor] or [NamedConstructor], extended attribute on it." should probably drop the comma.
