So the convention for spacer.gif in tables if people used the alt attribute at all would look like this: <td><img src="../images/spacer.gif" width="10" height="1" alt="*"></td> Remember? Arguments were that no one needed to hear 40 instances of "spacer" ;-)

Alternatively, if we forget the R, we can be talking about a lot of space, which is quite popular still in the science community. :D
