@class(optional)Contains one or more URIs which denote classification terms that apply to the entity
bearing this attribute.
@color(optional)Used to indicate visual appearance. Do not confuse this with the musical term 'color'
as used in pre-CMN notation.
@copyof(optional)Points to an element of which the current element is a copy.
@corresp(optional)Used to point to other elements that correspond to this one in a generic
fashion.
@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.
@endid(optional)Indicates the final element in a sequence of events to which the feature
applies.
@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.)
@extender(optional)Indicates the presence of an extension symbol, typically a line.
@follows(optional)points to one or more events in a user-defined collection that are known to be
predecessors of the current element.
@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.
@lendsym(optional)Symbol rendered at end of line.
@lendsym.size(optional)Holds the relative size of the line-end symbol.
@lform(optional)Describes the style of a line.
@lsegs(optional)Describes the number of segments into which a dashed or dotted line may be divided,
or
the number of "peaks" of a wavy line; a pair of space-separated values (minimum and
maximum, respectively) provides a range between which a rendering system-supplied
value
may fall, while a single value indicates a fixed amount of space; that is, the minimum
and
maximum values are equal.
@lstartsym(optional)Symbol rendered at start of line.
@lstartsym.size(optional)Holds the relative size of the line-start symbol.
@lwidth(optional)Width of a line.
@meiversion(recommended)Specifies a generic MEI version label. Allowed values are: "6.0-dev" (Version of MEI), "6.0-dev+anyStart" (Version of MEI All AnyStart customization)
@n(optional)Provides a number-like designation that indicates an element’s position in a sequence
of similar elements. May not contain space characters.
@next(optional)Used to point to the next event(s) in a user-defined collection.
@part(optional)Indicates the part in which the current feature should appear. Use 'all' when the
feature
should occur in every part or 'none' when the feature should not appear in any part.
@partstaff(optional)Signifies the part staff on which a notated feature occurs. Use 'all' when the
feature should occur on every staff.
@place(optional)Captures the placement of the item with respect to the staff with which it is
associated.
@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.
@precedes(optional)Points to one or more events in a user-defined collection that are known to be
successors of the current element.
@prev(optional)Points to the previous event(s) in a user-defined collection.
@resp(optional)Indicates the agent(s) responsible for some aspect of the text’s transcription,
editing, or encoding. Its value must point to one or more identifiers declared in
the
document header.
@sameas(optional)Points to an element that is the same as the current element but is not a literal
copy
of the current element.
@staff(optional)Signifies the staff on which a notated event occurs or to which a control event
applies. Mandatory when applicable.
@startid(optional)Holds a reference to the first element in a sequence of events to which the feature
applies.
@synch(optional)Points to elements that are synchronous with the current element.
@to(optional)Records a timestamp adjustment of a feature’s programmatically-determined location
in
terms of musical time; that is, beats.
@tstamp(optional)Encodes the onset time in terms of musical time, i.e., beats[.fractional beat part],
as expressed in the written time signature.
@tstamp2(optional)Encodes the ending point of an event, i.e., a count of measures plus a beat location
in the ending measure.
@type(optional)Designation which characterizes the element in some sense, using any convenient
classification scheme or typology that employs single-token labels.
@vgrp(optional)Provides a label for members of a vertically aligned group.
@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.
@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.
@xml:base(optional)Provides a base URI reference with which applications can resolve relative URI
references into absolute URI references.
@xml:id(optional)Regularizes the naming of an element and thus facilitates building links between it
and other resources. Each id attribute within a document must have a unique value.
@y(optional)Encodes a 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.
