That's correct.  I wrote the word Dictionary there, and I had a clear
idea what I had in mind, but I'm not sure whether that idea has been
written down anywhere.

The value would be a string, such as "foo" or "bar".  In the example
you gave, there are two parameters with the name title.  The
specification will say which of the two values will show up in the
dictionary, but I haven't studied the question of which one yet.

Rather than invent a new dictionary type, I think it make sense to use
the native one in the language (which in JavaScript is called Object),
which connects up with why modifying the dictionary doesn't mutate the
underlying URL.

I don't think we need to tackle that problem in the first version.
HTML has a very nice way of constructing URLs with query parameters
called the form element.
