I think if we stay with this SC wording for 2.4.5 we will need to make it clear that it 
is OK to have more than one link going to the same place on a web page.

Some sites have a repeat of the menu bar at the bottom of the delivery unit. (ie. site 
map, Home, products etc)

If each link has a unique function, we need to make clear the distinction between an 
exact copy of the link vs. different link text going to the same place..
