There are currently 2 types of Structural Modifiers:
<ul>
<li><a href="ddc.html">Data Driven Content</a> which identify URL paths that represent data
<li><a href="structparams.html">Structural Parameters</a> which identify parameters that represent application structure instead of user data
</ul>
Structural Modifiers can only be applied to <a href="contexts.html">Contexts</a>.
