Grace notes

Grace notes are encoded as graceGrp with the appropriate @attach and @grace. Preceding grace notes are encoded with @attach="pre", and ending (i.e., following) grace notes with @attach="post". For preceding grace notes, the acciaccature will have a @grace="unacc" and appogiature @grace="acc". For ending grace notes, the value is @grace="unknown". The grace groups will contain chord, note and beam. Note duration are encoded as standard MEI duration in @dur.

For wider compatibility, MEI import also supports grace notes encoded without being wrapped within a graceGrp. One limitation of this approach is that ending grace notes are not supported. The grace notes will always be attached to the following chord or note, or ignored if appearing at the end of a measure.
