Nit: I would write 'to generate documents' here.

This would become 'to generate PDF documents'

I didn't mean to also change this uppercase call from $$ to $. The
'exception' is until now only made when calling the inner infra from
the outer one. On this line, we are already in the inner infra so one
would use $$.

What is the purpose of the quotes here, given your recent commit of
qstrip in MESSAGE ?
