25 | That does not prevent the use of a three dimensional CRS. It just means that |

26 | only two coordinates will be specified in that 3D system. The veritcal coordinates are |

27 | specified separately and, for 3D systems, one of the linked wellDatums should represent |

28 | the vertical datum of that 3D system so that the height in the 3d system can be determined. </xsd:documentation> |
