It is not necessarily sufficient to look only at the physical and logical
usages when determining if a field is for the pen or touch. Some fields
are not contained in a sub-collection and thus only have an application
usage. Not checking the application usage in such cases causes us to
ignore the field entirely, which may lead to incorrect behavior.
