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.
    <!---
    <cfswitch expression = "#ThisTag.ExecutionMode#">
      <cfcase value = "start">
       <cfif IsStruct(attributes.EMPINFO)>
       <cfoutput>Error. Invalid data.</cfoutput>
       <cfexit method = "ExitTag">
       <cfelse>
       <cfquery name = "AddEmployee" datasource = "cfsnippets">
       INSERT INTO Employees
       (FirstName, LastName, Email, Phone, Department)
       VALUES
       <cfoutput>
       (
       `#StructFind(attributes.EMPINFO, "firstname")#' ,
       `#StructFind(attributes.EMPINFO, "lastname")#' ,
       `#StructFind(attributes.EMPINFO, "email")#' ,
       `#StructFind(attributes.EMPINFO, "phone")#' ,
