SEQUENCE number on recurrences

[sman@xxxxxxxxxxxx (Steve Mansour)]

Folks,

Say that you create a recurring event. Now let's say that you update the
DTSTART value of a single instance of that recurring event. Do you need
to bump the sequence number of just the single instance you changed or
do you bump the sequence number for all instances?

I wasn't clear on this after reading the Sequence Number text in RFC
2445.
