Remarks

All text changes are considered to be the replacement of oldText with newText. Insertion is a text change in which oldText is an empty string and newText a non-empty string. Deletion is a text change in which oldText is a non-empty string and newText is an empty string. Modification is a text change in which both oldText and newText are non-empty strings.

ITextChange objects are immutable.
