25 | <xsd:documentation>The name of the coordinate reference system in a particular naming system. |

26 | An optional short name (code) can also be specified. Specifying a well known system is highly desired. |

27 | An example would be to specify a name of 'WGS 84 / UTM zone 10N' with a code of '32610' in |
---|
28 | the 'EPSG' naming system. Note that specifying a name in the EPSG naming system is asserting |

29 | that the parameters in the EPSG database are appropriate for this CRS. This is |

30 | also true for any other naming system. If in doubt, contact your local geodesist.</xsd:documentation> |
