+          <p>When embedded in XHTML Turtle data blocks MUST be enclosed in CDATA sections. Those CDATA markers MUST be 
+          in Turtle comments. This will also make Turtle safe in polyglut documents served as both <code>text/html</code>
+          and <code>application/xhtml+xml</code>.</p>

+          <p>
+          It is possible to display the contents of script tags containing Turtle for use in examples or other guides
+          using Cascading Style Sheets Selectors Level 3 ([[SELECT]]).
+<pre class="example">
+script[type='text/turtle'] {
+  display:block;
+  white-space: pre;
+  font-family: monospace;
+}
+</pre>
+          However, this creates issues with polyglut documents. If you wish to display Turtle from script tags you 
+          SHOULD only use <code>text/html</code>.
