The pause properties are tied to the definition of the SSML break 
element, See:

  http://www.w3.org/TR/2004/PR-speech-synthesis-20040715/#S3.2.3

It notes: The break element is an empty element that controls the
pausing or other prosodic boundaries between words. I have added
www-voice to the thread, and perhaps the creators of SSML can
respond to your comments on prosodic boundaries.
