I've found this to be erratic at times :-}
Usually new fields show up.
But deleted fields are not removed. This, however, isn't a big problem since you can just remove the field in the designer.
Changing a field name results in the same thing - a new field is added with the new name but the old field is still there....
Bigger problems occur if, for example, relationships change....

All in all, it works great if you create from a stable database design (or create the DB from the model) - but if you are making frequent changes to the DB you'll eventually find yourself having to tweak the XML to avoid having to create a complete new model :-{
