      This document describes the Astronomical Data Query Language (ADQL). ADQL
      has been developed based on SQL92. This document describes the subset of
      the SQL grammar supported by ADQL. Special restrictions and extensions to
      SQL92 have been defined in order to support generic and astronomy
      specific operations.
