We are trying to index molecules. One method whereby a molecule
can be described is with a so called SMILES string.
This unfortunately, contains characters such as  (, [, : = etc.

We were rather hoping that specifying these as a literal  "...(,[,  "
might do the trick, but no luck. 

A search of the htdig site did not reveal how literals might be handled.

Are they? Could they be in  3.2?
