<li>the email address is marked in the binding as "read-only", meaning it
will only be bound from bean/xml to form, but not in the other

<li>The binding doesn't support all widget types yet.</li>
<li>Note how, in the XML binding, the date is formatted according XML
Schema date format in the XML, while it is displayed in another format
to the user, and is stored in the form model as a Java Date
object (useful for date-specific validations).</li>
