This element may also indicate a short pause or break for instruments *not* requiring breath. In such cases, it functions as a guide to phrasing. The starting point of the breath mark may be indicated by either a startid, tstamp, tstamp.ges, or tstamp.real attribute. It is a semantic error not to specify a starting point attribute.
Since the breath mark does not disrupt the normal tempo of a performance, it has no directly encode-able duration.
The default value for place for a breath mark is "above". Unless indicated by other attributes, a breath mark will be rendered as a comma-like symbol above the top line of the staff.
