[stringtemplate-interest] Question on using index variable(<i> and <i0>) in invoked template

[Jiwon Seo]

Thanks.

Actually I have one more question.
What I really want to do is to concatenate <i0> with a constant string
and pass it as an argument
as following:

<sorted:{s|<if(s)><insert("pos", "prefix"+<i0>)><endif>}; separator=";\n">

but it seems like it doesn't work with or without <>
