Hi Michael, All

We discussed your comments during WebEvents' 11-Oct-2011 call [1] and 
captured your comment #1 as [LC-7] and your comment #2 as [LC-6] in our 
LC disposition of comments document.

* Re LC-6 - we agree additional non-normative tutorial/Primer type 
information for the Touch Events spec would be useful. I created 
[Action-85] to track this request. If you and/or your colleagues wish to 
contribute to such information, please let me know. However, we do not 
think completion of this action should block this spec from progressing 
on the Recommendation track (and BTW, the next step will be another LCWD).

Regarding the interaction between touch events and mouse events, we 
agree additional non-normative text would be useful and think the 
information already included in section 7 of the spec [2] is sufficient. 
If you have additional non-normative text you want to propose, please 
send to public-webevents at w3.org so we can review it.

* Re LC-7 - Sangwhan agreed to address these two editorial comments (add 
units to attribute definitions and add a definition of preventDefault). 
I noticed he already made two related commits:


and the result is reflected in the latest Editor's Draft of the spec:


For the purposes of comment tracking, please let us know if our 
responses are OK or not.
