Discontinuities are characterized by crossing of connecting or projecting branches. A discontinuous element D and the highest located element E located between D and its governor exhibit an unidentity relation concerning their indices. Among these four indices, all index values are different, and no index values of one element are numerally contigue. In a stemma, the vertical dimension is called the hierarchy dimension, and the horizontal one time dimension. In order to deal with coordination, the theory provides the possibility to create a three-dimensional stemma.
Coordination is instituted by the repeated employment of previously used formation rules.
The first time these rules are enacted, they create a primary procedure , the second time is called secondary procedure asf. Structures that are created by different procedures are to be placed into different planes by the employment of procedure indices. This third dimension is called procedural time dimension. The procedural time dimension and the time dimension define the time plane, and the procedural time dimension and the hierarchy dimension define the procedural hierarchy plane. In order to capture and describe word order, I propose a theory called zone theory .
