the cap specification is adding the 'tombstone' property to
ical. the presence of a tombstone for a calendar component
indicates that the component has been deleted.

seems like the whole point of custom attributes is to allow
the specification to be extended where necessary. i suggest
adding an X-Tombstone attribute for deletions.

ical supports a sequence property for calendar components.
each time a modification is made to the component, the
sequence number is incremented. perhaps you should also add
an X-Sequence attribute.

these are the reasons to move to ical sooner rather than
later. the people who designed that spec have shipped
products that perform these tasks already, and they've done
the hard work of figuring out where the old standards are
lacking.
