The SEDRIS Data Representation Model
APPENDIX B - Constraints
Feature Edge Restrictions

Definition

The following restrictions apply.

  1. The <Location> instances within a <Feature Edge> shall be distinct (i.e., no 2 may have the same coordinates).

  2. <Feature Edges> may meet only at <Feature Nodes>, and <Feature Faces> may meet only along one or more <Feature Edges>.

  3. At feature topology level 2 or higher, no <Feature Edge> may intersect with or overlap another <Feature Edge>.

  4. At feature topology level 3, each <Feature Edge> forms part of the boundaries of exactly two <Feature Faces>.

Rationale

The path defined by the sequence of line segments which connect the consecutive <Locations> that make up a <Feature Edge> shall not intersect or overlap itself.
