Remarks

Mensural notes can have multiple stems and these may have various forms, directions, and types of flags. Multiple stem elements can be encoded as children of a single note. The attributes @pos, @length, @form, and @dir allow to encode different positions, lengths, forms, and directions for each these stems. The attributes @flag.pos and @flag.form also allow to encode different types of flags for each of the stems.

Constraints

A note with nested stem elements must not have @stem.* attributes.
