<xs:annotation>
<xs:documentation>
Sets the array base for any arrays used in the definition (that is, whether the first value is in position 0 or 1, etc.). This may be the data array in a delimited data file or the measure array for measures that are bundled and stored in a single location. Array base is generally set to either 0 or 1. There is no override provided as systems processing a record would use a consistent array base.
