Exception	Condition
ArgumentNullException	spansToInsert is null or a span in the list are null.
ArgumentOutOfRangeException	position is less than zero or greater than the number of spans. -or- spansToReplace is less than zero or position + spansToReplace is greater than the number of spans.
ArgumentException	An element of spansToInsert is neither an ITrackingSpan nor a string. -or- A span in spansToInsert would cause a duplicated projection. -or- A tracking span in spansToInsert is EdgeInclusive and does not cover its entire buffer, or is EdgePositive and does not abut the end of its buffer, or is EdgeNegative and does not abut the beginning of its buffer. (These checks are not performed if the projection buffer was created with the PermissiveEdgeInclusiveSourceSpans.) -or- Adding a text buffer containing one of the spansToInsert would create a cycle among a set of projection buffers.
