VOEvent Update

[Rob Seaman]

Perhaps the Avro / JSON tools will be able to handle the truth...er, STC?

In 2009, the normative recommendation also continued to support STC.
Note also that the author of STC was involved in the devising of the
strings like UTC-FK5-GEO. Perhaps we might improve the handling of these
in some fashion?

What does STC2 say to the issue?
