* <useAttribute> should be used when you want to create a Java
variable in the generated java file. <useAttribute> create a
variable in a jsp scope due to the jsp mechanism used to
initialize the java variable.
* <importAttribute> only import attribute in specified scope. So,
if you don't need the java variable, you should better use
<importAttribute>. In addition, <importAttribute> can import all
tiles' attributes in one shoot, which can not be done with
<useAttribute>.
