<div class="subhead">Stepping up through the views (tree of nested rendered templates)</div>

<table>

	<thead><tr><th>Title</th><th>Languages (+specialMessage)</th></tr></thead>

<div class="subhead">Setting contextual template parameters, accessible in all nested contexts as <em>~nameOfParameter</em>:</div>

<table>

	<thead><tr><th>Title</th><th>Languages (+specialMessage)</th></tr></thead>

</table>

<!---------------------- Third Example ---------------------->

<div class="subhead">Using the top-level data, accessible in all nested contexts as <em>~root</em>:</div>

<table>
