To me it reads ok. It's just written in an informal voice; that's
intentional. If we find that people find this style irritating, then
we can change the tone.

It might not look like it now, but this ain't no W3C Note; It's going
down the rec track. This was agreed to at the last face to face
meeting in Boston. There is precedence for this (xml schema, rdf,

Agreed. We will have a better idea after the next face 2 face meeting
(April 17th)... also I need to run the CSS processor over the document
to get the proper ToC. However, I won't process it until the document
is much more mature because the processor makes a mess.

Agreed. I will change everything to "XBL".

I don't understand. Can you please elaborate?

Yes, I have to take another screen-shot of the image. It's on my todo list.

Ah, of course! I will fix that. I should get into the practice of
putting my system language into Spanish to test stuff.

Still working that out.

Yeah, I figured that too... I will dump the XHTML examples and only do
HTML. When I first wrote this, I thought XHTML still had a future;-)

Yes, I agree the linking is very weak here. I will fix that soon, but
the current example my be dumped because I am starting to think that
XBL adds little value to it.

We will add that into the example.

I think there is a note there about that in the document. However,
that example may be dropped.

Those sections will be similar to each other. Some people might not
want to read the tutorial in chapter 1 and might just want to jump to
the more advanced examples in part 2...

I will clarify this in the primer a bit... however, it means that you
can't do the following:
<widget xmlns="http://e.com/ui"
   	alert("this will never work..");
   	alert("but this will!");

Yes, this section is fairly poor ATM.

Lachlan Hunt has just joined the working group to help us come up with
good examples.

We can definitely have that. Please send us more requests or send us
usage examples.

Thanks for the comments!

Kind regards,
