Ed,
Due to a problem with the way were reading in models, we were =
creating XSDAnnotations with null elements. We haven't quite solved =
that yet, but an interesting side effect is a NPE in the =
XSDAnnotationItemProvider. It would seem that the item provider should =
be a bit more fault tolerant as this exception takes down the property =
sheet page and clutters up the log. Here is the stack...

Lance,

I'd be more tempted to prevent null from being added to the list in the
first place...
