/**
* A dedicated editor for structured name. When the user collapses/expands
* the structured name, it will reparse or recompose the name, but only
* if the user has made changes. This distinction will be particularly
* obvious if the name has a non-standard structure. Consider this structure:
* first name="John Doe", family name="". As long as the user does not change
* the full name, expand and collapse will preserve this. However, if the user
* changes "John Doe" to "Jane Doe" and then expands the view, we will reparse
* and show first name="Jane", family name="Doe".
