negative begin time (offset value)

Negative begin time for the SMI animation is stil not allowed:

SInce the document end in SVG is always undetermined, a negative offset value 
in SVG is always an error.


As I know SVG and SMIL WG have agreed that negative time should be permited in 
SVG 1.1 and in the SVG 1.0 errata.
