[antlr-interest] Unspecified licenses for grammars on Antlr.org

[Ron Hunter-Duvar]

Hi,

I noticed that some of the grammars listed on 
http://www.antlr.org/grammar/list such as the Java 1.5 grammar have a 
license specified, but others do not. Is there some default license that 
is considered to apply to the unspecified ones? Are they considered 
public domain? Or are they considered property of the author(s) and 
would need to have a license negotiated to use? Of course, probably few 
if any of us here are lawyers, but I'm wondering what the community's 
view is.

Thanks,
Ron
