What is a note

A note in an XCF note pad has the following:

An 8 byte name
An 8 byte instance number
A 16 byte tag value
Note content, which is either null (no data) or 1024 bytes of data
A 12 byte connection identifier
A persistence attribute

When creating a note, the application provides the note name, note content, and persistence attribute. XCF sets the instance number and connection identifier. The creator of the note pad determines who has responsibility for setting the tag value, either the application or XCF.
