mei:measure

Records the location of a bar line.

Indicates whether or not a bar line is "controlling"; that is, if it
indicates a point of alignment across all the parts. Bar lines within a score are usually
controlling; that is, they "line up". Bar lines within parts may or may not be
controlling. When applied to <measure>, this attribute indicates the nature of the
right barline but not the left.

Points to an element of which the current element is a
copy.

Used to point to other elements that correspond to this one in a generic
fashion.

Identifies one or more metadata elements within the header, which are
understood to apply to the element bearing this attribute and its
content.

Specifies the intended meaning when a participant in a relationship is
itself a pointer.

Permits the current element to reference a facsimile surface or image zone
which corresponds to it.

Used for linking visually separate entities that form a single logical
entity, for example, multiple slurs broken across a system break that form a single
musical phrase. Also used to indicate a measure which metrically completes the current
one. Record the identifiers of the separately encoded components, excluding the one
carrying the attribute.

Provides a name or label for an element. The value may be any
string.

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.

Indicates the relationship between the content of a measure and the
prevailing meter.

Provides a number-like designation for an element.

Used to point to the next event(s) in a user-defined
collection.

Points to the previous event(s) in a user-defined
collection.

Indicates the function of the right bar line and is structurally
important.

Points to an element that is the same as the current element but is not a
literal copy of the current element.

Provide any sub-classification for the element, additional to that given
by its type attribute.

Points to elements that are synchronous with the current
element.

If takt bar lines are to be used, then the taktplace attribute may be used
to denote the staff location of the shortened bar line. The location may include staff
lines, spaces, and the spaces directly above and below the staff. The value ranges between
0 (just below the staff) to 2 * number of staff lines (directly above the staff). For
example, on a 5-line staff the lines would be numbered 1,3,5,7, and 9 while the spaces
would be numbered 0,2,4,6,8,10. For example, a value of '9' puts the bar line through the
top line of a 5-line staff.

Allows the use of one or more previously-undeclared URIs to identify
passive participants in a relationship; that is, the entities pointed
"to".

Characterization of target resource(s) using any convenient classification
scheme or typology.

Captures performed onset time in several forms; that is, ppq (MIDI clicks
and MusicXML 'divisions'), Humdrum **recip values, beats, seconds, or mensural duration
values.

Used to record the onset time in terms of ISO time.

Characterizes the element in some sense, using any convenient
classification scheme or typology.

Indicates the unit of measurement. Suggested values include: 1] byte; 2]
char; 3] cm; 4] in; 5] issue; 6] mm; 7] page; 8] pc; 9] pt; 10] px; 11] record; 12] vol;
13] vu

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.

Measurement of the horizontal dimension of an entity.

Defines whether a link occurs automatically or must be requested by the
user.

Characterization of the relationship between resources. The value of the
role attribute must be a URI.

Defines how a remote resource is rendered.

Provides a base URI reference with which applications can resolve relative
URI references into absolute URI references.

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.
