<!--
    The MusicXML format is designed to represent musical scores,
    specifically common western musical notation from the 17th
    century onwards. It is designed as an interchange format
    for notation, analysis, retrieval, and performance
    applications. Therefore it is intended to be sufficient,
    not optimal, for these applications.
    
    The MusicXML format is based on the MuseData and Humdrum
    formats. Humdrum explicitly represents the two-dimensional
    nature of musical scores by a 2-D layout notation. Since the
    XML format is hierarchical, we cannot do this explicitly.
    Instead, there are two top-level formats:
    
    partwise.dtd   Represents scores by part/instrument
    timewise.dtd   Represents scores by time/measure
    
    Thus partwise.dtd contains measures within each part,
    while timewise.dtd contains parts within each measure.
    XSLT stylesheets are provided to convert between the
    two formats.
    
    The partwise and timewise score DTDs represent a single
    movement of music. Multiple movements or other musical
    collections are presented using opus.dtd. An opus
    document contains XLinks to individual scores.
    
    Suggested use:
    
    <!DOCTYPE score-partwise PUBLIC
        "-//Recordare//DTD MusicXML 3.0 Partwise//EN"
        "http://www.musicxml.org/dtds/partwise.dtd">
    
    This DTD is made up of a series of component DTD modules,
    all of which are included here.
-->

<!-- Entities -->

<!--
    The partwise and timewise entities are used with
    conditional sections to control the differences between
    the partwise and timewise DTDs. The values for these
    entities are what distinguish the partwise and timewise
    DTD files.
-->
<!ENTITY % partwise "INCLUDE">
<!ENTITY % timewise "IGNORE">

<!-- Component DTD modules -->

<!--
    The common DTD module contains the entities and elements
    that are shared among multiple component DTDs.

<!--
    The layout DTD module contains formatting information for
    pages, systems, staves, and measures.

<!--
    The identity DTD module contains identification and
    metadata elements.
-->
<!ENTITY % identity PUBLIC

<!--
    The attributes DTD module contains elements that usually
    change at the start of a measure, such as key signatures,
    time signatures, and clefs.
-->

<!--
    The direction DTD module contains elements for musical
    directions not tied to individual notes. This includes
    harmony and chord symbol elements.
