Delivery Units And Frames

SC 2.4.4 says that delivery units should have titles. Good. 

 

For HTML and frames, I believe that the delivery units are the Frame Pages
and the Frameset Page (or pages). 

 

But "How to Meet SC 2.4.4" says providing title attributes on the <frame>
element is an HTML technique for meeting 2.4.4. 

 

In what sense is the title attribute on a <frame> element a title for a
delivery unit? What delivery unit?
