CCXML Voxeo 1.0 Development Guide

This documentation is for CCXML 1.0-Voxeo, which has been superceded by CCXML 1.0-W3C. The CCXML-Voxeo platform is not being updated any longer. The CCXML 1.0-W3C version, however, has many new features and is actively being enhanced. If you're writing a new CCXML application, you should use CCXML 1.0-W3C.

<log> element
