endid(optional)Indicates the final element in a sequence of events to which the feature
applies.
Value conforms to data.URI.
evaluate(optional)Specifies the intended meaning when a participant in a relationship is itself a
pointer. Allowed values are: "all" (If an element pointed to is itself a pointer, then the target of that pointer will
be taken, and so on, until an element is found which is not a pointer.), "one" (If an element pointed to is itself a pointer, then its target (whether a pointer
or not) is taken as the target of this pointer.), "none" (No further evaluation of targets is carried out beyond that needed to find the
element(s) specified in plist or target attribute.)
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.
part(optional)Indicates the part in which the current feature should appear. Use '%all' when the
feature should occur in every part.
One or more values of datatype
a string matching the following regular expression: "(%all|#[\i][\c]+)"
, separated by spaces.
partstaff(optional)Signifies the part staff on which a notated feature occurs. Use '%all' when the
feature should occur on every staff.
One or more values of datatype
a string matching the following regular expression: "(%all|\d+(-\d+)?)"
, separated by spaces.
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.
