Overall, I think this is excellent, and much improved from the first 
version.  One quibble, though reasonable people might disagree with my 
position on this:

You say on Slide 25 that <redefine> is deprecated, but that is followed in 
the CR draft with a feedback request asking the community whether such 
deprecation is a good idea.  Speaking for myself (not IBM), I think it's 
too early to deprecate redefine.  It's a supported feature of 1.0, and as 
far as I know it's widely used.  Although there's some optimism that 
<override> will be a good substitute, that's as yet unproven and in any 
case deprecating features that users have already deployed at best tends 
to make them nervous.

So, I would prefer that you said:  "(The Schema working group is proposing 
to deprecate <redefine>)", or perhaps "is considering deprecating 
<redefine>".  YMMV.

Hi Folks,

Here are the updates I made to the XML Schema 1.1 Tutorial:

    1. I received many excellent comments and 
       incorporated them.

    2. I created 20 lab exercises. I recommend 
       working the exercises as you read through 
       the tutorial.


Here is the updated tutorial:

Here is the updated tutorial + labs + examples:

As always, please let me know if there is anything in the tutorial that is 
unclear or if you find a typo. 

/Roger
