LGPL (non-GPL) code in xmlsitemap module

I am moving the issue to the project queue.

I am not sure which version of the project contains that file, nor if the file is still included in the last release.

The original library has been significantly modified (by my own work) to ease use with the module and work with jQuery rather than its own JavaScript. Furthermore the library is unmaintained (no updates since 2005). Once I took over maintainership of the module and re-evaluated this code, I had e-mailed the author about the situation, but never heard back. Hence it's my belief that it is a derivative work that the code is fine. I left the original copyright/LGPL in the XSL file, so if I need to remove/change/update that, please let me know.

It is true that a derivative work of a LGPL code is still under LGPL License, but it is also true that LGPL License is compatible with GPL License (http://www.gnu.org/licenses/license-list.html).

About the files available from third-party sites that can be committed in drupal.org repository, we have some exceptions and I think this case is included in those exceptions (the committed file has been changed, and the original file is not anymore developed).

"We had to hack it to bits to make it work" is one of the usual grounds for an exception to the "no 3rd party code" rule, which seems to apply here. LGPL is also in-bound compatible. From a Legal standpoint this looks fine to me, and maintaining the original copyright statement is polite and proper.

Actually technically you're supposed to include the original copyright/license block and add your own as well, which would be preferred. See section 2.2 of:

http://softwarefreedom.org/resources/2007/gpl-non-gpl-collaboration.html

So I think all that needs to be done here is some minor tweaks to the docblock in question. Otherwise it looks fine unless the Infra folks have any other specific objection.

Thanks! Committed #7 to CVS.
