Youtube if you're interested . I think I managed to get the important parts
right despite my nerves. I've given this sort of talk four times now, and
as a result I've collected some feedback and questions from the developers
I've talked to.

Two things: 1. Added in markup or dynamically?  The draft says it can't be
added dynamically just in case...  2.  The draft itself is a little unclear
on "is".  Early in the text, the reference was changed to say that these
will be custom tags, in other words <x-map> instead of <select
is="x-map">.  Mozilla's x-tags is currently operating under that assumption
as well.

tried applying and unapplying the 'is' attribute to remix the unordered
list using a template without success.
