Permission to use, copy, modify and distribute the DocBook XML DTD and its accompanying documentation for any purpose and without fee is hereby granted in perpetuity, provided that the above copyright notice and this paragraph appear in all copies. The copyright holders make no representation about the suitability of the DTD for any purpose. It is provided as is without expressed or implied warranty.
If you modify the DocBook DTD in any way, except for declaring and referencing additional sets of general entities and declaring additional notations, label your DTD as a variant of DocBook. See the maintenance documentation for more information.
DocBook and the DocBookStylesheets are 100% free software, meeting all terms of the GNU Free Software Definition, the Debian Free Software Guidelines, and the Open Source Definition. That means they're free not only in the sense that they're no-cost, but also in the sense that you're free to use them for any purpose, modify them in any way you want, and distribute your modified versions, without unnecessary restrictions and without needing to ask anybody for permission.
However, you are asked to distribute modified version responsibly, meaning that you should name and label them variants so that users will not confuse them with the standard versions.
As far as specific licenses, the wording of the license distributed with the DocBookStylesheets is pretty much the same as the MIT/X Consortium license, including the advertising clause, which states that:
the names of individuals credited with contribution to this software shall not be used in advertising or otherwise to promote the sale, use or other dealings in this Software without prior written authorization from the individuals in question
Though the license distributed with the DocBookDtd does not closely parallel the wording of any other well-known license, it is a 100% free software license.
Both DocBook and the DocBookStylesheets are also copyrighted. The copyrights ensure that anybody who redistributes modified versions has to do it under the terms of the same 100% free-software license the copyright holders chose, so it all stays free.

Moin Moin GPL
The GNU General Public License, version 2 (short: GNU GPLv2 or simply GPLv2) is a very popular Free Software License originally written by Richard Stallman for the GNU project and now kept and developed by the Free Software Foundation.
Free in the context of this license means the freedom of the user of the software. Basically, the license gives everyone the right to do anything with the software provided they abide by certain (limited) restrictions: code licensed under GPL cannot be distributed in closed source programs.
The MoinMoin code is licensed under the GPLv2 or (at the user's option) any later version (except some 3rd party modules we use that are licensed under other Free Software licenses compatible with the GPL).
Consequences of this are, for example:
Changes released by the community will be open source
Encouragement and beneficiary of global collaboration.
