This does not tell you how to declare ownership of your code.  It just 
says that for convenient source code distribution with Maxima, it should 
be possible to redistribute your code under GPL.

Other agreements such as BSD, are less restrictive and essentially say 
that you can distribute this stuff any way you want, to anyone.  I find 
GPL to be annoying because commercial entities sometimes refuse to take 
such code.

I can give code to Maxima under BSD and it can be redistributed under 
GPL, but I could also then give the code to (say) Boeing and they can 
use it too.  If I declare my code to be available ONLY under GPL then 
Boeing (or some other company) may refuse it.

It is possible to say your code is available under BSD or GPL, I 
suppose.  But I am not a lawyer either.
