Both lines below consist of multiple letter I's separated by one or more spaces and are
identical div elements in the .smil file. The only difference between them is that
the first div has xml:space="default" and the second div has xml:space="preserve".
I I I I I I I I I I
I I I I I I I I I I
The spacing between the I's should all the be same on the first line.
The spacing between the I's should increase along the second line.
