Hi all, I've uploaded my proposal: http://rniwa.com/editing/undomanager.html
Summary of changes: - *Section 3.2 Automatic transactions* is rewritten - Removed *A proper sequence of automatic transactions* - Added *3.2.1. Undoability and Redoability of Automatic Transactions*to clarify when an automatic transaction can be unapplied and reapplied safely - isReapply argument is added to apply method of Transaction interface - isAutomatic attribute is added to Transaction interface - Partial interfaces are added for Document and Element interfaces to define undoManager and undoScope IDL attributes - label attribute of Transaction interface can return null now, and the spec allows UAs to use a part of the value as supposed to the whole (e.g. when it's too long) - Ryosuke
