h-event is currently a Microformats Draft Specification. As part of issue #1, we should determine if (and how) h-event is ready to become a Microformats Specification and thus subject to more explicit change control.
Per the process: http://microformats.org/wiki/process#Specifications
There are a number of preconditions to be satisfied. Anyone can help document if (and how) those preconditions are satisfied and we can use this issue to track that.
