       <p>
-          The LD Patch grammar shares most of its production rules with [[!Turtle]], which are extended to allow variables in the <a class="internalDFN" href="#grammar-production-subject">subject</a> and <a class="internalDFN" href="#grammar-production-object">object</a> positions.
+          Production labels consisting of a number and a final 's', e.g. [135s], reference the production with that number in the <a href="http://www.w3.org/TR/sparql11-query/#sparqlGrammar">SPARQL 1.1 Query Language grammar</a> [[!sparql11-query]]. Production labels consisting of a number and a final 't', e.g. [6t], reference the production with that number in the <a href="http://www.w3.org/TR/turtle/#sec-grammar-grammar">Turtle grammar</a> [[!Turtle]]. A production label containing an extra trailing '*' denotes a modified rule, e.g. [10t*] and [12t*].
