basicTypes.xsd 2002-04-15 Some generic simpleContent types for use in GML Utility type. Allowable values and their approximate semantics are: innapplicable - the object does not have a value missing - the value is not available template - the value will be available later unknown - the value cannot be computed withheld - the value is not divulged Specific communities may agree to assign more strict semantics when these terms are used in a particular context. Name with an (optional) authority. Text token. If the codeSpace attribute is present, then its value is a reference to a source of validation for the value, such as the organisation who assigned the value, or the dictionary from which it is taken. Value on a nominal scale, or a typed null. Text token. If a codeSpace attribute is present, then its value is a reference to a Reference System for the value, a dictionary or code list. List of values on a uniform nominal scale. List of text tokens. A member of the list may be a typed null. If a codeSpace attribute is present, then its value is a reference to a Reference System for the value, a dictionary or code list. Number with a scale. The value of uom (Units Of Measure) attribute is a reference to a Reference System for the amount, either a ratio or interval scale. Number with a scale, or a typed null. If a uom (Units Of Measure) attribute is present, then its value is a reference to a Reference System for the amount, either a ratio or interval scale. List of numbers with a uniform scale. A member of the list may be a typed null. If a uom (Units Of Measure) attribute is present, then its value is a reference to a Reference System for the amount, either a ratio or interval scale. Tables or arrays of tuples. May be used for text-encoding of values from a table. Actually just a string, but allows the user to indicate which characters are used as separators. The value of the 'cs' attribute is the separator for coordinate values, and the value of the 'ts' attribute gives the tuple separator (a single space by default); the default values may be changed to reflect local usage. Defaults to CSV within a tuple, space between tuples. However, any string content will be schema-valid. Utility type used in various places - e.g. to indicate the direction of topological objects; "+" for forwards, or "-" for backwards.
