Example<!--- This view-only example shows the use of IsStruct. --->
<p>This file is similar to addemployee.cfm, which is called by StructNew,
StructClear, and StructDelete. It is an example of a custom tag used to
add employees. Employee information is passed through the employee
structure (the EMPINFO attribute). In UNIX, you must also add the Emp_ID.
