Notes
The first example indicates complete certainty that a single, entire line of text has been lost.The second example indicates complete certainty that some unknown number of entire lines of text have been lost.For indications of uncertainty about whether lines of text have been lost or not, see Possibility that letters have been completely lost.NB: values of extent greater than 1, when combined with unit="line" are unsupported by the standard xslts; therefore, each separate lost line should be encoded as a separate gap, with appropriate line breaks (vel sim.) separating them.
