Hi all, I've updated the document: http://rniwa.com/editing/undomanager.html per discussions.
Summary of changes: - "transaction" is renamed to "DOM transaction" - The value of isAutomatic is read immediately before the transaction is applied - Swapped the definition of clearUndo and clearRedo in the non-normative section to match the rest of the spec - transact() no longer attempts to merge transactions when there are no transactions to merge with - Incorporated Aryeh's feedback - DOM state now include IDL properties and their values Best, Ryosuke Niwa Software Engineer Google Inc.
