#### Example 1: Write a Template Section
```rpgle
      *--------------------------------------------------------------
      * This example demonstrates calling RXS_ComposeSection() to write the template
      *  section 'content'. This section would be defined in the XML template EXAMPLE
      *  like so:
      *   ::content
      *   <element>...</element>
      *--------------------------------------------------------------
     H DFTACTGRP(*NO) BNDDIR('RXSBND') ACTGRP(*CALLER)
