The version attribute was added in Version 1.1 for the score-partwise and score-timewise documents. It provides
an easier way to get version information than through the MusicXML public ID. The default value is 1.0 to make
it possible for programs that handle later versions to distinguish earlier version files reliably. Programs
that write MusicXML 1.1 or later files should set this attribute.
