Type	Element	Description	Use
ID	div	matching of different musical phrases so that they are rendered simultaneously in a a synchronized manner	To match or synchronize different musical phrases. Matching could be delivered either visually (as different staves) or audably (by playing together different phrases).

In SGML the sequence connector is used to connect generic identifiers to indicate the order in which elements must follow one another. Identifiers are separated with commas. The SGML sequence indictes linear sequence, not simultaneous sequence. The MML match attribute indicates simultaneous sequences -- things that happen together, such as different music instruments playing together.

The match attribute is used for notation purposes to align different staffs in different divisions. In a case such as the following, the user agent needs to be informed that the two divisions with different clefs are part of the same musical theme. In notation the two different divisions should line up bar for bar.

Example
Markup	What happens...
<div clef="C" octave="4" note="4" match="1"> ...division content... </div> <div clef="bass" octave="2" match="1"> ...division content... </div>	The two divisions (cleff "C" and "bass" match (ie they are synchornized).
