Subject: Add error status SC_STATUS_OUTSIDE_DOCUMENT that is set when
 operations are attempted on a position outside the document. Positions are
 checked earlier to prevent actions partly succeeding. This is implemented
 with a new exception type Failure which should be caught by platform layer's
 API handling code to produce a more granular error status.
