MusicXML allows part-name and part-name-display in the score-part element. If part-name-display is given, it overrides the part-name for display. The first staff uses only part-name, while the second one (same part-name) overrides it with a custom text. Similar for the part-abbreviation used in subsequent staves. Part name abbrv.
