<!--
	MIDI XML is an XML representation of standard MIDI files for
	MIDI 1.0. Unlike standard MIDI files, it can have timestamps
	present as either absolute or delta values. This makes it
	convenient as an intermediate format to convert from the
	MusicXML format and other formats where note on and note off
	are not represented as discrete events. To convert to
	Standard MIDI Files, delta values must be used.

	Suggested use:

	<!DOCTYPE MIDIFile PUBLIC

<!--
	For Standard MIDI Files, channels are required; events
	are not rechannelized.

<!--
	The MMA MIDI DTD contains the definitions of all MIDI
	events. Its regular address is:

	http://www.midi.org/dtds/MIDIEvents10.dtd

	For convenience, we include a local copy with our
	definition, and reference that here.

	one or the other throughout the MIDI XML file. Timestamps
	are numeric values measured in MIDI ticks.

	Standard MIDI File events include MIDI Channel messages,

	The XMFPatchTypePrefix meta-event is described in

	The meta-event hex 21 has been used, though unofficially,

<!--
	TrackCount indicate the number of tracks in a file: 1 for

<!--
	How many ticks in a beat (MIDI quarter note).

	TimestampType should be Delta or Absolute. Indicates the
	element name to look for in the initial timestamp in each

	Tracks contain the musical data and are made up of a series
	of events. The track number attribute is required.
