<xs:complexType name="tremolo">
  <xs:annotation>
    <xs:documentation>While using repeater beams was the original method for indicating tremolos, often playback and display are not well-enough integrated in an application to make that feasible. The tremolo ornament can be used to indicate either single-note or double-note tremolos. Single-note tremolos use the single type, while double-note tremolos use the start and stop types. The default is "single" for compatibility with Version 1.1. The text of the element indicates the number of tremolo marks and is an integer from 0 to 6. Note that the number of attached beams is not included in this value, but is represented separately using the beam element.</xs:documentation>
