&lt;p&gt;This file is similar to addemployee.cfm, which is called by StructNew,
StructClear, and StructDelete. To test this file, copy the
&amp;LT;CFELSEIF&amp;GT; statement to the appropriate place in 
addemployee.cfm. 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.

&lt;cfswitch expression = &quot;#ThisTag.ExecutionMode#&quot;&gt;
  &lt;cfcase value = &quot;start&quot;&gt;
   &lt;cfif StructIsEmpty(attributes.EMPINFO)&gt;
    &lt;cfoutput&gt;Error. No employee data was passed.&lt;/cfoutput&gt;
