Hi Anna and Team!

CC-ing this message to Cocoon Dev list, cause it raises a more general
requirement for possibility to combine input modules with other input
modules in sitemap substitution values (see below for a use-case).

I see.

Quite natural desire. Unfortunately, this is not supported (I hope yet), but
it would be very useful.

Don't bother so much about stupid questions, if it were really stupid then
I'd simply ignore it ;)

Yes, that's true. The documentation for Input module is very short, but I
hope that the sample (/samples/modules) demonstrates most of the
possibilities.
