I have added a "handle" attribute to the "technicalSpec" element and 
also added it to our documentation. See:
* <>
* <>
* <>
* <>

The following handles are currently in use (in our test samples):
* XHTML10 - XHTML 1.0
* CSS20 - CSS Level 2
* SMIL10 - SMIL 1.0

* QUICKTIME - Apple QuickTime
* ECMA262 - JavaScript/ECMAScript
* MSDHTML - Microsoft DHTML Reference (for elements such as embed)
* WMA9 - Windows Media Audio
* WMV9 - Windows Media Video
* MIDI - Musical Instruments Digital Interface (MIDI)

* OFCOMAUDIODESC - OFCOM Guidance on Standards for Audio Description 
(this is actually not a technology)
* OFCOMCAPTIONS - OFCOM Guidance on Standards for Subtitling (see above)

Best regards,
