Per ACTION-133: Write proposal for issue-22, I propose the following text to create an optional rr:languageIdentifier to be used in conjunction with rr:SQLQuery:

1.3 SQL Conformance ΒΆ2
http://www.w3.org/2001/sw/rdb2rdf/r2rml/#sql-conformance

-In places where SQL expressions are allowed, these MUST conform to Core SQL 2008.}
+This document specifies the behavior of R2RML applied to SQL 2008 databases. The <code>rr:languageIdentifier</code> property can be used to identify other language versions where database queries are embedded in R2RML documents.}


3.3.1.3 rr:languageIdentifier
below http://www.w3.org/2001/sw/rdb2rdf/r2rml/#LogicalTable_SQLQuery_Property

+    <h5><a name="LogicalTable_languageIdentifier_Property" id="LogicalTable_languageIdentifier_Property"></a>3.3.1.2 rr:languageIdentifier</h5>
+    <pre class="vocab">rr:languageIdentifier rdfs:range xsd:string .
+</pre>
+
+    <p>
+      While R2RML is defined only with respect to SQL 2008[<cite><a href="#SQL1">SQL1</a></cite>][<cite><a style="" href="#SQL2">SQL2</a></cite>], the it can be extended to apply to other languages.
+      The <code>rr:languageIdentifier</code> property is <em class="rfc2119">MAY</em> be used to identify the language embedded in the object of the <a href="#LogicalTable_SQLQuery_Property">rr:SQLQuery</a> property.
+      The identifier &lt;<a href="http://www.w3.org/2001/sw/rdb2rdf/r2rml/SQL2008">http://www.w3.org/2001/sw/rdb2rdf/r2rml/SQL2008</a>&gt; corresponds to SQL 2008.
+    </p>
+
+    <pre class="ex-mapping">
+[] rr:languageIdentifier <http://www.w3.org/TR/r2rml/SQL2008>
+   rr:SQLQuery """...""" .
+</pre>
+
+    <p>If the SQLQuery language is not SQL 2008 and there is no convenient language identifier for the SQLQuery language, a blank node may be used to indicate that the SQLQuery language is unknown.</p>
+
+    <pre class="ex-mapping">
+[] rr:languageIdentifier [] .
+</pre>
