3- Erratas

These are SMIL 2.1 [second edition] errata that need to be updated into http://www.w3.org/2004/06/EditedREC-SMIL20-errata

Time manipulation Module

1- formula:(2.0*0.75= = 1.5)
this looks like a bug to me should be
(2.0*0.75 = 1.5)

2- AD is the associated Active Duration.

Added in the following praragraph:

Let t_ps be a time in parent simple time, and B be the begin time, and O be the accumulated synchronization offset for an element, measured in parent simple time. Let AD be the Active Duration.
