I am not really a fan of this for a few reasons:

1. <x-____> is immediately recognizable to anyone viewing source, as opposed to
scanning for a dash somewhere in a name

2. Do we really want to end up with this: <-sometag> or <sometag->, if not, are
we going to institute another restriction that the tag cannot begin or end with
a dash?

3. Is namespacing for tag names really as much a concern as JS variables? I
would argue that it isn't, because 99% of the time you know what tags are
included in your app.

4. The Firefox implementation is basically 3 feet from touching down on the
tarmac, and though this isn't a huge change (I'm guessing), is it really
providing a significant value?

Let me know what you folks thing about the above.
