   ${if whatever                         \
            {  ${if   somewhat          \
                          {yes}                                \
                          { ${if       something } }    \
            }                                     \
            {  ${if   somewhat  }      \
      }

Obviously, replace "whatever", "somewhat" and "something" with
suitable conditions ( per http://exim.org/exim-html-4.69/doc/html/spec_html/index.html#toc0144 ).
I wasn't sure if you meant the two "somewhat"s to be the same....
and I used the "syntactic sugar" of assumed "yes" and "no" results.

Now, re-reading your original, I'm unsure where your "and" comes in?
Perhaps it's implied by the embedding.
