Look good, models the hierarchy using hierarchy, easy to write a conversion
for.

<xsl:template match="menu">
<html>
<head>
<title></title>
</head>
<body>
<ul>
<xsl:apply-templates select="item"/>
</ul>
</body>
</html>
</xsl:template>
<xsl:template match="item">
<li>
<a href="{url}">
<xsl:value-of select="name"/>
</a>
<xsl:if test="item">
<ul>
<xsl:apply-templates select="item"/>
</ul>
</xsl:if>
</li>
</xsl:template>

But if you have multiple top-level items, do they all have @parent = 0? How do
you know which item is inside which. I think you're better off using the
earlier XML vocabulary. If you want to add numbering, add
<xsl:number level="multiple"/>
as the first child of li element, just before a element.
