Smarty will recognize <link
linkend="api.assign">assigned</link>
<link linkend="language.syntax.variables">variables</link>
embedded in "double quotes" so long as the variable name contains only numbers,
letters, under_scores and brackets[].
See <ulink url="&url.php-manual;language.variables">naming</ulink>
for more detail.

<listitem><para>
With any other characters, for example a .period or
<literal>$object>reference</literal>, then the variable must be
surrounded by <literal>`backticks`</literal>.
</para></listitem>
<listitem><para>You cannot embed
<link linkend="language.modifiers">modifiers</link>, they must always
be applied outside of quotes.
