[stringtemplate-interest] Including optional keywords as parameters to String Template

[jevitha]

Hi ,

ya .. but that should be sent only if it exists in my input ... so is there
an equivalent of ? in string template rewrite rules?
So that in the example

className : (('.module')? name1 ) slashedName ;

.module will be sent only if it occurs ?

in parser and tree grammar ? is supported, is it the same with string
template rewrite rule ...
