I've thought about it some more, and it may be difficult to do with the
way the add() and remove() are currently defined with no return value.
I assume that means you're intending for these functions to modify the
other methods that do modifications actually return a new string, not
Then, there's also the question of assuming the token delimiter will
always be a space. Will there need to be a way to specify what the
delimiter is, or is that intended to be dependant upon the language?
For example, in HTML .className would return a DOMTokenString delimited
by spaces, but in FooBarML it may be semi-colons, commas, or anything else.

I think fixing the grammar of this paragraph and adding one more
sentence won't be too confusing

The space character (U+0020) is not special in the method's arguments.
In HTML, XHTML, SVG and MathML it is impossible for an element to
belong to a class whose name contains a space character and thus, for
these languages, the method would return no nodes if one of its
arguments contained a space. This does not, however, prevent other
languages from allowing spaces in class names.
