Attributes
@coll, @color, @dis, @dis.place, @dur, @endho, @endid, @extender, @ho, @label, @layer, @lendsym, @lendsym.size, @lform, @lsegs, @lstartsym, @lstartsym.size, @lwidth, @plist, @staff, @startho, @startid, @tstamp, @tstamp2, @type, @vo, @xml:id
@coll(optional)Indicates whether the octave displacement should be performed simultaneously with the written notes, i.e., "coll' ottava". Unlike other octave signs which are indicated by broken lines, coll' ottava typically uses an unbroken line or a series of longer broken lines, ending with a short vertical stroke. See Read, p. 47-48. Allowed values are: "coll" (Coll' ottava (with the octave).)
@color(optional)Used to indicate visual appearance. Do not confuse this with the musical term 'color' as used in pre-CMN notation.
@dis(optional)Records the amount of octave displacement.
@dis.place(optional)Records the direction of octave displacement.
@dur(optional)When a duration cannot be represented as a single power-of-two value, multiple space-separated values that add up to the total duration may be used.
@endho(optional)Records the horizontal adjustment of a feature’s programmatically-determined end point.
@endid(optional)Indicates the final element in a sequence of events to which the feature applies.
@extender(optional)Indicates the presence of an extension symbol, typically a line.
@ho(optional)Records a horizontal adjustment to a feature’s programmatically-determined location in terms of staff interline distance; that is, in units of 1/2 the distance between adjacent staff lines.
@label(optional)Captures text to be used to generate a label for the element to which it’s attached, a "tool tip" or prefatory text, for example. Should not be used to record document content.
@layer(optional)Identifies the layer to which a feature applies.

Remarks

The @dis and @dis.place attributes record the amount and direction of displacement, respectively. The @lform and @lwidth attributes capture the appearance of the continuation line associated with the octave displacement. The starting point of the octave displacement may be indicated by either a @startid, @tstamp, @tstamp.ges, or @tstamp.real attribute, while the ending point may be recorded by either a @dur, @dur.ges, @endid, or @tstamp2 attribute. It is a semantic error not to specify one starting and one ending type of attribute. Also, note that the @dur attribute is not required because the octave displacement can be visually instantaneous.

Constraints

Must have one of the attributes: startid, tstamp, tstamp.ges or tstamp.real.
Must have one of the attributes: dur, dur.ges, endid, or tstamp2.
