Maybe -- I'll have to see whether I think I can change this to "byte sequence and metadata" and fill in the steps from there without dropping below the level of detail I have informally tried to keep to in this intended-to-be-moderately-lightweight (but not intended to be misleading, either) document. ht - -- Henry S.
