Re: Difference between freeze and hold

Dear Ramalingam,

Freeze and hold both extend the rendering duration of an associated 
element for the duration of the parent time container.

For a <par> element, 'freeze' and 'hold' are functionally equivalent.
For a <seq> element, a 'freeze' attribute extends the rendering to
   the end of the current element's scope, while 'hold' extends the
   element to the end of the parent (<seq>) time container.

In other words, if you have three slides in a <seq> and you want to have 
an object extend for the entire duration of the <seq>, use fill='hold'.

This (and the rest of SMIL) is explained in the upcoming book:
   SMIL 2.0: Interactive Multimedia for Web and Mobile Devices
   D.C.A. Bulterman & L. Rutledge
   Springer-Verlag 2004.
(The book will be out on April 15.)
