Re: Two errors regarding event types in SCXML

Hi Bento and Jim,

Thanks a lot for finding the issues, Bento!
And thank you for your response as the (former) main Editor of the spec, Jim!

It seems to me that we should fix two typos within the SCXML
Recommendation:
  https://www.w3.org/TR/2015/REC-scxml-20150901/

If that is what we should do, I'd like to talk within the W3C Team
to clarify what we can do.

Thanks,

Kazuyuki
