Explanations of symbologies used in Attribute Values
Where the attribute values are limited to a defined set of values, these are shown without quotation marks.
Where the attribute value is an actual name or descriptive text, an example of the type of value is shown within quotation marks: e.g. "xyz road".
Where a value is not required, or cannot be determined, the {empty} is shown to indicate that no value is a valid entry.
