Is a DOMTokenList an "array" that can be passed to gEBCN?
It could be defined to accept either a space separated string or an
array. Using the [Overloads] extended attributed defined in the
Language Bindings for DOM Specifications draft [1], it could be defined
like this:
NodeList getElementsByClassName(in DOMString classNames);
[Overloads=getElementsByClassName]
NodeList getElementsByClassNameArray(in DOMString[] classNames);
For ECMAScript, that effectively means that getElementsByClassName() can
be called with either a space separated string of class names or an array.

I agree with Simon here. Allowing arrays to be passed in doesn't add any
extra value and complicates the implementation significantly. I think
that the by far most common case is going to be passing a single class
name, so adding multiple ways of passing multiple class names seems like
overkill.
