Dear Alexandre and EmotionML implementers,

Thank you very much for implementing EmotionML, Alexandre!
Also your thorough review on the EmotionML [1] specification and
the Implementation Report [2] is really appreciated.

We are very sorry it took much longer to get consensus about how to
respond to you and wrap-up the procedure [3] to publish EmotionML
as a W3C Recommendation.

We the W3C Multimodal Interaction Working Group have already fixed
typos in the spec and added necessary clarifications to it.  In
addition, we have generated an updated version of the schema [5, 6].

Now the remaining question is how to deal with your comments on the
Implementation Report which wouldn't change the spec itself.

I talked within the W3C Team about what we should have done from the
W3C Process viewpoint, and it seems we need to make sure that there
are enough implementation experience for the following two features
which were not explicitly described in the published Implementation
Report [2].

Feature1:
    In Section 2.4.1 of the sepc [1], there is a feature "The end value
    MUST be greater than or equal to the start value", which is not
    checked in the Implementation Report.

Feature2:
    In Section 2.1.2 of the spec [1], there is a feature "a typical use
    case is expected to be embedding an <emotion> into some other
    markup", which is not checked in the Implementation Report.

We have already checked with EmotionML implementers (including you)
and it seems we can get several implementations for the above two
features as well.

Now we would like to ask all the EmotionML implementers to respond
to this message and express if the aobve features are implmented
so that we can finalize the procedure and publish EmotionML as a
W3C Recommendation.
