<![CDATA[<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %>]]>

<title>The <literal>authorize</literal> Tag</title>

<para>

|
||||

|
||||
but discouraged.</para></footnote>. The first approach uses a <link xlink:href="el-access-we">web-security expression</link>,
|
||||
specified in the <literal>access</literal> attribute of the tag.
