There are already some words on this topic in the spec:

page 108:

There is a demand for handling weld lines exceeding the actual contact polygon of the involved parts, which is presented in the following figure:

Standard conform polygons may well exceed the contact area. However, χMCF version 3.1 does not state anything about the physical meaning or the implications for CAE and CAM. Hence, later versions of χMCF may specify details about what should happen with exceeding parts of a weld line in CAE and CAM. In CAE, for example, hexahedron or tetrahedron could be generated on the exceeding polygons, if their height or thickness is provided.
