//REVIEW: this method, SynchronizeDataItemsFromContentsOfElement(), is confusing because it is not static and yet it
//creates a new DataSet, ignoring its member variable _dataset. In MigrateData, we are changing things in the datadiv and
//want to both change the values in our _dataset but also have those changes pushed throughout the DOM via the following
//call to UpdateDomFromDataSet().
MigrateData(data);

//REVIEW: the other methods here are, for some reason, acting on a local DataSet, "data".
//But then this one is acting on the member variable. First Q: why is the rest of this method acting on a local variable dataset?
