@endid(optional)Indicates the final element in a sequence of events to which the feature
applies.
Value conforms to data.URI.
@func(optional)Records the function of a tempo indication. Allowed values are: "continuous" (Marks a gradual change of tempo, such as "accel." or "rit."), "instantaneous" (Represents a static tempo instruction, such as a textual term like "Adagio", a
metronome marking like "♩=70", or a combination of text and metronome
indication.), "metricmod" (Captures a change in pulse rate (tempo) and/or pulse grouping (subdivision) in an
"equation" of the form [tempo before change] = [tempo after change].), "precedente" (Indicates a change in pulse rate (tempo) and/or pulse grouping (subdivision) in an
"equation" of the form [tempo after change] = [tempo before change]. The term
"precedente" often appears following the "equation" to distinguish this kind of
historical usage from the modern metric modulation form.)
@layer(optional)Identifies the layer to which a feature applies.
One or more values of datatype positiveInteger, separated by spaces.
@mm(optional)Used to describe tempo in terms of beats (often the meter signature denominator) per
minute, ala M.M. (Maelzel’s Metronome). Do not confuse this attribute with midi.bpm
or
midi.mspb. In MIDI, a beat is always defined as a quarter note, *not the numerator
of the
time signature or the metronomic indication*.
Value conforms to data.TEMPOVALUE.
@mm.dots(optional)Records the number of augmentation dots required by a dotted metronome unit.
Value conforms to data.AUGMENTDOT.
@mm.unit(optional)Captures the metronomic unit.
Value conforms to data.DURATION.
@plist(optional)When the target attribute is present, plist identifies the active participants; that
is, those entities pointed "from", in a relationship with the specified target(s).
When
the target attribute is not present, it identifies participants in a mutual
relationship.
One or more values from data.URI, separated by spaces.
@staff(optional)Signifies the staff on which a notated event occurs or to which a control event
applies. Mandatory when applicable.
One or more values of datatype positiveInteger, separated by spaces.
@startid(optional)Holds a reference to the first element in a sequence of events to which the feature
applies.
Value conforms to data.URI.
@tstamp(optional)Encodes the onset time in terms of musical time, i.e., beats[.fractional beat part],
as expressed in the written time signature.
Value conforms to data.BEAT.
@tstamp2(optional)Encodes the ending point of an event, i.e., a count of measures plus a beat location
in the ending measure.
Value conforms to data.MEASUREBEAT.
