@felixcheung Yes. This PR will just make the support available for
highlighting the SPARQL query syntax, so that any interpreter can use it as
language of choice. The interpreter development is still in progress and is
bit specific to the SPARQL server implementation that we have, hence we are
working on it to make it more generic so can be used for any SPARQL endpoint. ---
