att.barring

Attributes that capture the placement of bar lines.
Module
MEI.shared
Attributes
bar.len, bar.method, bar.place
bar.len(optional)States the length of barlines in virtual units. The value must be greater than 0 and is typically equal to 2 times (the number of staff lines - 1); e.g., a value of '8' for a 5-line staff. Value is a decimal number.
bar.method(optional)Records the method of barring. Value conforms to data.BARMETHOD.
bar.place(optional)Denotes the staff location of bar lines, if the length is non-standard; that is, not equal to 2 times (the number of staff lines - 1). Value conforms to data.STAFFLOC.

<remarks>
<p>The location may include staff lines, the spaces between the lines, and the spaces directly above and below the staff. The value ranges between 0 (just below the staff) to 2 * number of staff lines (directly above the staff). For example, on a 5-line staff the lines would be numbered 1, 3, 5, 7, and 9 while the spaces would be numbered 0, 2, 4, 6, 8, and 10. So, a value of '9' puts the bar line through the top line of the staff.</p>
