op:dimension( $column-builder-plan as map:map, $dimension as xs:unsignedInt ) as map:map
Summary
Sets the vector dimension for the column created by op:add-column. It only applies when the column's type is set to "vector". If the vector to be extracted does not have the same dimension, the value will be rejected. There's no default dimension. Vectors of all dimensions are extracted.
