Attributes
@amount (optional) Records the amount of detuning. The decimal values should be rendered as a fraction (or an integer plus a fraction) along with the bend symbol. Value conforms to data.BEND.AMOUNT . att.bend.ges
@bezier (optional) Records the placement of Bezier control points as a series of pairs of space-separated values; e.g., 19 45 -32 118. One or more values, each consisting of a sequence of decimal and decimal sub-values. att.curvature
@bulge (optional) Describes a curve as one or more pairs of values with respect to an imaginary line connecting the starting and ending points of the curve. The first value captures a distance to the left (positive value) or right (negative value) of the line, expressed in virtual units. The second value of each pair represents a point along the line, expressed as a percentage of the line's length. N.B. An MEI virtual unit (VU) is half the distance between adjacent staff lines. One or more of decimal. att.curvature
@color (optional) Used to indicate visual appearance. Do not confuse this with the musical term 'color' as used in pre-CMN notation. Value conforms to data.COLOR . att.color
@copyof (optional) Points to an element of which the current element is a copy. Value conforms to data.URI . att.common.anl
@corresp (optional) Used to point to other elements that correspond to this one in a generic fashion. One or more values from data.URI , separated by spaces. att.common.anl

@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.) att.targeteval
@facs (optional) Permits the current element to reference a facsimile surface or image zone which corresponds to it. One or more values from data.URI , separated by spaces. att.facsimile
@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. Value conforms to data.MEASUREMENTREL . att.visualoffset.ho
@label (optional) Provides a name or label for an element. The value may be any string. Value of datatype string. att.commonPart
@layer (optional) Identifies the layer to which a feature applies. One or more values of datatype positiveInteger, separated by spaces. att.layerident
@lform (optional) Describes the line style of a curve. Value conforms to data.LINEFORM . att.curverend
@lwidth (optional) Width of a curved line. Value conforms to data.LINEWIDTH . att.curverend
@n (optional) Provides a number-like designation for an element. Value conforms to token . att.common
@next (optional) Used to point to the next event(s) in a user-defined collection. One or more values from data.URI , separated by spaces. att.common.anl
@plist (optional) Contains a space separated list of references that identify active participants in a collection/relationship, such as notes under a phrase mark; that is, the entities pointed "from". One or more values from data.URI , separated by spaces. att.plist
@prev (optional) Points to the previous event(s) in a user-defined collection. One or more values from data.URI , separated by spaces. att.common.anl
@sameas (optional) Points to an element that is the same as the current element but is not a literal copy of the current element. One or more values from data.URI , separated by spaces. att.common.anl
@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. att.staffident
@startho (optional) Records the horizontal adjustment of a feature's programmatically-determined start point. Value conforms to data.MEASUREMENTREL . att.visualoffset2.ho
@startid (optional) Holds a reference to the first element in a sequence of events to which the feature applies. Value conforms to data.URI . att.startid
@startto (optional) Records a timestamp adjustment of a feature's programmatically-determined start point. Value conforms to data.TSTAMPOFFSET . att.visualoffset2.to
@startvo (optional) Records a vertical adjustment of a feature's programmatically-determined start point. Value conforms to data.MEASUREMENTREL . att.visualoffset2.vo
@subtype (optional) Provide any sub-classification for the element, additional to that given by its type attribute. Value of datatype NMTOKEN. att.typed
@synch (optional) Points to elements that are synchronous with the current element. One or more values from data.URI , separated by spaces. att.common.anl
@to (optional) Records a timestamp adjustment of a feature's programmatically-determined location in terms of musical time; that is, beats. Value conforms to data.TSTAMPOFFSET . att.visualoffset.to
@tstamp (optional) Encodes the onset time in terms of musical time, i.e., beats[.fractional_beat_part]. Value conforms to data.BEAT . att.timestamp.musical
@tstamp.ges (optional) Captures performed onset time in several forms; that is, ppq (MIDI clicks and MusicXML 'divisions'), Humdrum **recip values, beats, seconds, or mensural duration values. Value conforms to data.DURATION.gestural . att.timestamp.performed
@tstamp.real (optional) Used to record the onset time in terms of ISO time. Value conforms to data.ISOTIME . att.timestamp.performed
@tstamp2 (optional) Encodes the ending point of an event in terms of musical time, i.e., a count of measures plus a beat location. Value conforms to data.MEASUREBEAT . att.timestamp2.musical
@type (optional) Characterizes the element in some sense, using any convenient classification scheme or typology. Value of datatype NMTOKEN. att.typed
@vo (optional) Records the vertical adjustment of 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. Value conforms to data.MEASUREMENTREL . att.visualoffset.vo
@when (optional) Indicates the point of occurrence of this feature along a time line. Its value must be the ID of a when element elsewhere in the document. Value conforms to data.URI . att.alignment
@x (optional) Encodes an x coordinate for a feature in an output coordinate system. When it is necessary to record the placement of a feature in a facsimile image, use the facs attribute. Value of datatype decimal. att.xy
@x2 (optional) Encodes the optional 2nd x coordinate. Value of datatype decimal. att.xy2
@xml:base (optional) Provides a base URI reference with which applications can resolve relative URI references into absolute URI references. Value conforms to data.URI . att.commonPart

@y (optional) Encodes an y coordinate for a feature in an output coordinate system. When it is necessary to record the placement of a feature in a facsimile image, use the facs attribute. Value of datatype decimal. att.xy
@y2 (optional) Encodes the optional 2nd y coordinate. Value of datatype decimal. att.xy2
