[stringtemplate-interest] How to call a template from another when using formal args

[Marziou, Gael]

OK I understood how to pass attributes in arguments of another template, I just found that I did not need to enclose them within '$' chars.
So in my example, I rewrote it this way and it worked:

String templates = 
	"group test; " + 
	"zero(var) ::= <<$equals(var=var, value=0)$>> " + 
	"equals(var, value) ::= <<$var$ = $value$>>";
