                             <p>In this extremly short sample, we're defining some highlighting rules for when Ace detectes a <code>&lt;![CDATA</code> tag. When one is encountered, the tokenizer moves from <code>start</code> into the <code>cdata</code> state. It remains there, applying the <code>text</code> token to any string it encounters. Finally, when it hits a closing <code>]&gt;</code> symbol, it returns to the <code>start</code> state and continues to tokenize anything else.</p>
