This diagram shows the relationship between the elements of the schema. The boxes represent entities. The lines between the boxes represent relationships. The numbers at each end of the connecting lines show the minimum and maximum number of entities at each end of the relationship.
For example, each document has a root element note-set. It contains zero or more day-notes elements, each of which represents a
set of notes in one day (and in only one state). Each
day-notes element pertains to one and
only one note-set.

For day-summary, see Section 5.4, “The day-summary element:
information about the field day”. For the elements related
to day-summary, see Section 5.7, “The day-annotation elements”. For the para element, see Section 5.15, “The narrative elements”.
Section 5.8, “
The form element: records for one
kind of bird
” describes the form element and its related elements.
