DML: Dimensional Markup Language - Version 2.0
This file (DTD) defines DML feature elements.
All coordinates are in a common "part" coordinate system. An
optional coordinate system to use for reporting feature parameter
values (i.e. x,y,z coordinates) is used to transform results into
other coordinate systems.
All surface normal vectors point away from the material surface.
All vectors are normalized.
Units are specified in the file header and apply to all features
(can not specify units on a feature-by-feature basis).
When angles are used to define partial arcs or cylinders, the right-hand
rule is used to define direction. If the thumb of the right-hand
is placed in the direction of the specified surface normal, then the
fingers curl from the start point on the arc toward increasing angles.

A curve defined by a set of points. First point is start of
curve, last is end, others lie between in order as listed.
Minimum of two points needed but that is not enforced. Application
code should check that at least two points exist. Points do not have
to be coplanar.

A constant cross section surface defined by profile curves
and an extent vector. Profile curves are represented by
point data (measured points). The vector is used to sort
the points into cross sections. The nominal data is
sufficient to perform an analysis of the measured data
and will be used if the measured data is not supplied.
vector: Sort direction.
