Although as Dirk pointed out, SVG distinguishes <title> elements that 
are children of the root element vs children of other elements.  The 
<title> that is a child of the root element gives the title of the 
entire element, while a <title> child of another element in the document 
describes only that element (like title="" does in HTML).
