[Musicxml export] - Composite articulations not exported
The attached example lists out all composite articulations found in the articulations palette. Many of them are exported as a single articulation such as staccato, and most of them can't be exported, e.g., the ones at bar 2. I included the single soft-accent because it doesn't export at all. The xml file shows correct output, and the order of some items placed in the articulation tag should be followed. Usually, staccato should be the first, and tenuto the last, intervened by lots of accents.
