[stringtemplate-interest] How do I pass two variable (one is a multivariable) to a template?

[jerry wang]

Hi, Hoang
  Maybe you should try using 'it' as the default argument, and another
specified for 'Entity.name'
eg:
test(value) ::= <<
   <value.list:element(value.name); separator="\n\n">
>>

element(name) ::= <<
   <name> <it.name>;
>>
