Thanks for your prompt replies Boris, Rick and Sangwhan!

Given this feedback, I propose the description of the variadic method 
change from:

[[
<https://dvcs.w3.org/hg/webevents/raw-file/v1/touchevents.html#methods-1>

Creates a TouchList object consisting of zero or more Touch objects.
]]

to:

[[
Creates a TouchList object consisting of zero or more Touch objects. 
Calling this method with no arguments creates a TouchList with no 
objects in it and length 0.
]]

Comments on the proposal are welcome, but please send them as soon as 
possible and include a specific proposal that would satisfy/address your 
proposal. In the absence of any comments, I will include this proposal 
in LC#2.

Cathy - is there a test case(s) for this variadic method?

-Thanks, AB
