<title><xsl:value-of select="category"/></title>
</head>
<body>
<!-- Header -->
<h1><xsl:value-of select="category"/></h1>
<ul>
<xsl:for-each select="composition">

<li><xsl:value-of select="title"/></li>
</xsl:for-each>
</ul>
<!-- Body -->
<xsl:apply-templates select="composer">
<xsl:sort select="name/last_name"/>
<xsl:sort select="name/first_name"/>
<xsl:sort select="name/middle_name"/>
</xsl:apply-templates>
