Check out the org.apache.struts.taglib.logic.IterateTei class -- you will see
that the "type" attribute is used to define the Java data type of the scripting
variable that is exposed to the page. This does not generally matter if you
only access the exposed bean with custom tags, but does matter if you try to
access it with scriptlets -- the default data type is java.lang.Object, so you
would have to cast all your method calls.
The same general pattern is followed in other places where the "type" attribute
is used for the same purpose, such as <bean:define>.
