Conditional Tags Examples
<if> Simple Conditional Execution 
Only shows a customer from the customer list if they are living in the USA.
<choose> Mutually Exclusive Conditional Execution
Customers from the USA will be printed in blue, those from Canada in red, and
others in green.
Custom Logic Tag
JSTL exposes in its API the abstract class ConditionalTagSupport
to facilitate the implementation of custom conditional tags that leverage the
standard conditional behavior defined in JSTL. This example shows the custom tag
<usCustomer> that returns true
if its customer attribute value points to a customer who lives in the USA. It
can be used both in the context of a simple conditional execution and in the context
of a mutually conditional execution by exposing the result of the conditional
execution in a JSP page attribute by using the tag attribute var.
