Issue:Cannot include a template call that uses a 2nd template variable

Description:	Template calls that use 2nd template variables cannot be included.

Problem

I have the following template:

{{ {{{format}}}
| variable1=xxx
| variable2=yyy
}}

I cannot generate an include line that works with this template, as include wants a real name, but my template uses a passed in variable as a template call.

I would like to be able to use the following inside a dpl call:

include={ {{{format}}} }:variable1:variable2
