Attributes:
- navigability: physical possibility to travel between net element A and B and the direction (obligatory;
xs:string)
- Possible values:
- AB: it's possible to go from elementA to elementB and not vice versa
- BA: it's possible to go from elementB to elementA and not vice versa
- Both: it's possible to go from elementB to elementA and vice versa
- None: it's not possible to go from elementB to elementA and vice versa,
- positionOnA: the information at which end of the elementA the relation is valid (optional;
xs:integer)
- Possible values:
- 0: beginning of netElement
- 1: end of netElement,
- positionOnB: the information at which end of the elementB the relation is valid (optional;
xs:integer)
- Possible values:
- 0: beginning of netElement
- 1: end of netElement,
- id: the identifier of the object; this can be either of type xs:ID or UUID (obligatory;
xs:ID); compare: Dev:Identities

*Notice:
Elements may have different parent elements. As a consequence they may be used in different contexts.
Please, consider this as well as a user of this wiki as when developing this documentation further.
Aspects that are only relevant with respect to one of several parents should be explained exclusively in the documentation of the respective parent element.
