An entire line completely lost (extent certain or uncertain)

Notes

1. The first example indicates complete certainty that a single, entire line of text has been lost.
2. The second example indicates complete certainty that some unknown number of entire lines of text have been lost.
3. The third and fourth examples indicate that some number of lines have been lost from the top or bottom of the text respectively (Krummrey-Panciera do not distinguist between these two cases, although some transcription schemes do). These cases were previously grouped under a separate heading ("One or more lines completely lost at the beginning or end of a text or fragment (extent uncertain)") in an older version of the Guidelines.
4. For indications of uncertainty about whether lines of text have been lost or not, see Possibility that letters have been completely lost.
5. 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.
