Title: Corrigenda should provide
comprehensive data changes
Author: Markus Scherer
provides Changes to
the Content of UnicodeData.txt for a Bidi_Class correction. However, there
are dozens of properties, and dozens of .txt files, in the Unicode Character
Database. Some properties are derived from others, some files present
properties in other forms (e.g., DerivedBidiClass.txt), and some properties
should be synchronized with others for consistent behavior.
When a corrigendum changes property values, it should spell out all of the
changes to derived files and dependent property values. If no other value
needs to be changed, that should be stated.
