<remarks xml:lang="en">
<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
<val>9</val> puts the bar line through the top line of the staff.</p>
<p>This attribute is ignored if the value of the style attribute is
