The angle that orients the local axes relative to the spatialcoordinate system. Give one angle for a 2D system (rotation aboutthe vertical axis) and up to three for a 3D system (for exampleEuler angles, or rotations about the X, Y and Z axes);transformationMethod determines how multiple angles are interpreted.Repeat for each angle.

The uniform scale factor of the local coordinate system relative tothe spatial coordinate system. The default is 1.0 (no scaling). Avalue above 1.0 means local coordinates represent larger distancesthan the corresponding spatial coordinates, and a value below 1.0smaller distances.

Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
