ATTRIBUTE

The ATTRIBUTE sub-descriptor defines the attribute name of a data element and description of a data(name|desc). This sub-descriptor is usually used in conjunction with the TYPE and POSITION sub-descriptors.

Example:

    GAV Data File       GAV Schema File
    _____________       _______________

    79.351 1 mountain   GAV
    45.447 2 mountain   CATEGORY: VARIABLE
    28.235 3 mountain   SEPARATOR_CHARS: " "
    32.589 4 field      DATA: TYPE(DOUBLE)  ATTRIBUTE(Length|Length) POSITION(1)
    19.326 5 field      DATA: TYPE(INTEGER) ATTRIBUTE(ID|identify) POSITION(2)
			DATA: TYPE(STRING)  ATTRIBUTE(Region|Region) POSITION(3)

    Resulting Records (Length, ContourID, Region)
    _____________________________________________

    (79.351, 1, "mountain")
    (45.447, 2, "mountain")
    (28.235, 3, "mountain")
    (32.589, 4, "field")
    (19.326, 5, "field")

In this example, the fields in each record represent the following attributes associated with a set of contours: the length of the contour, the contour's ID number, and the region in which the contour lies.
