Members 
curve (direct member of att.curvature)

Attributes 
@bezier(optional)Records the placement of Bezier control points as a series of pairs of
spaceseparated values; e.g., 19 45 32 118.
One or more values, each consisting of a sequence of decimal and decimal subvalues.
att.curvature
@bulge(optional)Describes a curve as one or more pairs of values with respect to an imaginary line
connecting the starting and ending points of the curve. The first value captures a
distance to the left (positive value) or right (negative value) of the line, expressed
in virtual units. The second value of each pair represents a point along the line,
expressed as a percentage of the line's length. N.B. An MEI virtual unit (VU) is half
the distance between adjacent staff lines.
One or more of decimal.
att.curvature
@curvedir(optional)Describes a curve with a generic term indicating the direction of curvature.
Allowed values are:
"above" (Upward curve.), "below" (Downward curve.), "mixed" (A "meandering" curve, both above and below the items it pertains to.)att.curvature
