mei:annot

Contains a reference to a field or element in another descriptive encoding
system to which this MEI element is comparable.

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.

Records the number of augmentation dots required by a dotted
duration.

Records duration using optionally dotted, relative durational values
provided by the data.DURATION datatype. When the duration is "irrational", as is sometimes
the case with tuplets, multiple space-separated values that add up to the total duration
may be used. When dotted values are present, the dots attribute must be
ignored.

Records performed duration information that differs from the written
duration. Its value may be expressed in several forms; that is, ppq (MIDI clicks and
MusicXML 'divisions'), Humdrum **recip values, beats, seconds, or mensural duration
values.

Indicates the final element in a sequence of events to which the feature
applies.

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.

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

Identifies the layer to which a feature applies.

Provides a number-like designation for an element.

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

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".

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

Indicates the agent(s) responsible for some aspect of the text's creation,
transcription, editing, or encoding. Its value must point to one or more identifiers
declared in the document header.

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

Contains a list of one or more pointers indicating the sources which
attest to a given reading. Each value should correspond to the ID of a <source>
element located in the document header.

Signifies the staff on which a notated event occurs or to which a control
event applies. Mandatory when applicable.

Holds a reference to the first element in a sequence of events to which
the feature applies.

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.

Specifies the transliteration technique used.

Encodes the onset time in terms of musical time, i.e.,
beats[.fractional_beat_part].

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.

Encodes the ending point of an event in terms of musical time, i.e., a
count of measures plus a beat location.

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

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.

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.

Identifies the language of the element's content. The values for this
attribute are language 'tags' as defined in BCP 47. All language tags that make use of
private use sub-tags must be documented in a corresponding language element in the MEI
header whose id attribute is the same as the language tag's value.
