StyleSheet interface, href of type string can be null?

 From the StyleSheet interface in the Style Sheets spec:

readonly attribute DOMString href;
If the style sheet is a linked style sheet, the value of its 
attribute is its location. For inline style sheets, the value of this 
attribute is null.

Should strings ever be null? Should the value of this attribute for 
inline style sheets be empty string instead of null?
