Attributes
@label, @left, @metcon, @n, @right, @type, @xml:id
@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. Value is plain text.
<measure>att.commonatt.labelled@label
@left(optional)Indicates the visual rendition of the left bar line. It is present here only for facilitation of translation from legacy encodings which use it. Usually, it can be safely ignored. Value conforms to data.BARRENDITION.
<measure>att.measure.log@left
@metcon(optional)Indicates the relationship between the content of a measure and the prevailing meter. Value conforms to data.BOOLEAN.
<measure>att.measure.logatt.meterConformance.bar@metcon
@n(optional)Provides a number-like designation that indicates an element’s position in a sequence of similar elements. May not contain space characters. Value conforms to data.WORD.
<measure>att.nNumberLike@n
@right(optional)Indicates the function of the right bar line and is structurally important. Value conforms to data.BARRENDITION.
<measure>att.measure.log@right
@type(optional)Designation which characterizes the element in some sense, using any convenient classification scheme or typology that employs single-token labels. One or more values of datatype NMTOKEN, separated by spaces.
<measure>att.commonatt.typed@type
@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. Value is a valid xml:id.
<measure>att.commonatt.id@xml:id
(MEI.shared) Attributes common to many elements.
(MEI.shared) Attributes that uniquely identify an element.
@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. Value is a valid xml:id.
(MEI.shared)
@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. Value is plain text.
(MEI.shared) Attributes which can be used to classify features.
@type(optional)Designation which characterizes the element in some sense, using any convenient classification scheme or typology that employs single-token labels. One or more values of datatype NMTOKEN, separated by spaces.
(MEI.gestural) Gestural domain attributes. The tstamp.ges and tstamp.real attributes encode the onset time of the measure. In reality, this is usually the same as the onset time of the first event in the measure.
(MEI.cmn) Logical domain attributes. The n attribute contains a name or number associated with the measure (Read, p. 445). Often, this is an integer, but not always. For example, some measures, especially incomplete measures or those under an ending mark, may have labels that contain an integer plus a suffix, such as '12a'. Measures may even have labels, especially in editorial or analytical uses of MEI, that are entirely non-numeric strings. Measure numbers may be machine-generated instead of encoding them in the markup. However, an explicit measure number should restart numbering with the given value. The join attribute may be used to indicate another measure which metrically completes the current, incomplete one.
@left(optional)Indicates the visual rendition of the left bar line. It is present here only for facilitation of translation from legacy encodings which use it. Usually, it can be safely ignored. Value conforms to data.BARRENDITION.
@right(optional)Indicates the function of the right bar line and is structurally important. Value conforms to data.BARRENDITION.
(MEI.shared) Attributes that provide information about a measure's conformance to the prevailing meter.
@metcon(optional)Indicates the relationship between the content of a measure and the prevailing meter. Value conforms to data.BOOLEAN.
(MEI.shared) Attributes used to supply a number-like designation for an element.
@n(optional)Provides a number-like designation that indicates an element’s position in a sequence of similar elements. May not contain space characters. Value conforms to data.WORD.
@left(optional)Indicates the visual rendition of the left bar line. It is present here only for facilitation of translation from legacy encodings which use it. Usually, it can be safely ignored. Value conforms to data.BARRENDITION.
@right(optional)Indicates the function of the right bar line and is structurally important. Value conforms to data.BARRENDITION.
@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. Value is plain text.
@metcon(optional)Indicates the relationship between the content of a measure and the prevailing meter. Value conforms to data.BOOLEAN.
@n(optional)Provides a number-like designation that indicates an element’s position in a sequence of similar elements. May not contain space characters. Value conforms to data.WORD.
@type(optional)Designation which characterizes the element in some sense, using any convenient classification scheme or typology that employs single-token labels. One or more values of datatype NMTOKEN, separated by spaces.
@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. Value is a valid xml:id.

Remarks

In MEI, the <measure> element is a grouping mechanism for events and control events. Pointing attributes make it possible to connect this element to other internal or external entities, such as media objects or annotations. The @width attribute may be used to capture the width of the measure for interchange with music printing systems that utilize this information for printing.
