This commit reverts commit 89418d13.
The reverted commit will be applied in another branch (probably 'adql-2.1') as
it is part of the next release of ADQL-Lib.
This GitHub repository contains the sources of 3 libraries implementing [IVOA](http://www.ivoa.net/"International Virtual Observatory Alliance") standards and protocols:
*[ADQL](http://www.ivoa.net/documents/latest/ADQL.html"Astronomical Data Query Language")
*[UWS-1.1](http://www.ivoa.net/documents/UWS/20161024/index.html"Universal Worker Service pattern")
_**NOTE:** Support of ADQL-2.1 currently under development. For the moment, TAP
is still using ADQL-2.0 by default._
### Documentation
