Maybe I’m misunderstanding but you can pass template
parameters as arguments to nested templates. As in,
/Page
{{aha|output=hello}}
/Tempate:aha
{{echo|{{{output}}}}}
/Template:echo
{{{1}}}
The content of page will be “hello”. I used a named parameter
so that the example is clearer; that isn’t necessary.
Hope it helps.
