If you specify the setters then you also need to specify how this 
affects the value of the "href" attribute in the DOM.  For example, in 
Gecko if you have an <a href="foo#bar"> which has base URI 
"http://example.com/" and you set anchor.hash on that anchor to "baz", 
then the attribute value is changed to "http://example.com/foo#baz".  I 
can't speak to what happens in other browsers.
