endid(optional)Indicates the final element in a sequence of events to which the feature

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(required)Indicates the function of the mark, usually implying a corresponding form. Allowed values are: "coda" (Coda (SMuFL E048 or Unicode 1D10C).), "segno" (Segno (SMuFL E047 or Unicode 1D10B).), "dalSegno" (Dal segno (SMuFL E045 or Unicode 1D109).), "daCapo" (Da capo (SMuFL E046 or Unicode 1D10A).), "fine" (Fine.

layer(optional)Identifies the layer to which a feature applies.

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

When

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.
