Each element (ie, Component, Skeleton and Model) is capable of storing four pieces
of documentation - Notes and Data Book text (to be entered by the user), and an Audit
Trail - listing changes from the previous version to the current version - and a
Status report - highlighting whether the element has been materially changed since
last checked (generated by the system). Version control of each of these elements
is also managed by RingtailXL as its development proceeds.
