Re: Two errors regarding event types in SCXML

Hi Bento and Jim,
adding Philippe to CC

I talked with Philippe Le Hegaret, the W3C VP, Technical Strategy, about how to
handle the bug reports for SCXML again, and our suggestion is creating a
dedicated GitHub repository to maintain the SCXML specification:
  https://www.w3.org/TR/2015/REC-scxml-20150901/
and its Errata document:
  https://www.w3.org/2015/08/scxml-errata.html

As you might know, the latest W3C Process Document:
  https://www.w3.org/policies/process/#no-group-maintenance
let the W3C Team maintain the specification depending on the level of bugs/fixes
if there is no WG any more.

So we've created a dedicated GitHub repository:
  https://github.com/w3c/scxml
based on the original contents on the W3C CVS server:
  https://www.w3.org/Voice/Group/2005/HST/
to maintain the SCXML spec and its errata document.

For further discussion/fixes, please use the above GitHub repository. For
example, you can create a GitHub Issue to point to the existing bugs being
discussed on the www-voice list.

Thanks,

Kazuyuki
