DocBook XSL 1.78.1 copyright status

[Andy Hatton <andy.hatton@oracle.com>]

Hi,

I have been asked to investigate/verify the copyright status for the 
DocBook 1.78.1 stylesheets.

The distribution includes the COPYING file, which includes various 
copyright statements.

The copyrights run up to 2012, but 1.78.1 was released in 2013 (I 
think). The same statements are included in the current snapshot 
distribution.

Is this just an oversight, or has the copyright situation changed after 
2012?

Thanks
