<blockquote> It seems as if I cant use an Xpath in the name attribute of the call-template element. How can I get around this? </blockquote> Good question, +1. You can't. But you can use instead <code><xsl:apply-templates></code>. Here is a quick demo: <pre><code><xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:double="double" xmlns:incr="incr" xmlns:my="my:my" exclude-result-prefixes="double incr my" > <xsl:output method="text"/> <double:double/> <incr:incr/> <xsl:variable name="vFuncDouble" select="document('')/*/double:*[1]"/> <xsl:variable name="vFuncIncr" select="document('')/*/incr:*[1]"/> <xsl:function name="my:double"> <xsl:param name="arg1" /> <xsl:sequence select="2*$arg1"/> </xsl:function> <xsl:function name="my:incr"> <xsl:param name="arg1" /> <xsl:sequence select="1+$arg1"/> </xsl:function> <xsl:template name="double" match="double:*"> <xsl:param name="arg1"/> <xsl:sequence select="my:double($arg1)"/> </xsl:template> <xsl:template name="incr" match="incr:*"> <xsl:param name="arg1"/> <xsl:sequence select="my:incr($arg1)"/> </xsl:template> <xsl:function name="my:apply"> <xsl:param name="pFun" as="element()"/> <xsl:param name="arg1"/> <xsl:apply-templates select="$pFun"> <xsl:with-param name="arg1" select="$arg1"/> </xsl:apply-templates> </xsl:function> <xsl:template match="/"> <xsl:sequence select="my:apply($vFuncIncr, my:apply($vFuncDouble,2))"/> </xsl:template> </xsl:stylesheet> </code></pre> When this transformation is applied on any XML document (not used), the wanted result is produced: <pre><code>5 </code></pre> Do note: One can pass as parameter (the first argument) to <code>my:apply()</code> any "function" and <code>my:apply()</code> will apply it to its second argument. Using this same principle <a href="http://fxsl.sf.net" rel="nofollow">the FXSL library</a> implemented Higher Order Functions (HOFs) in XSLT 1.0 and XSLT 2.0 -- <a href="http://conferences.idealliance.org/extreme/html/2006/Novatchev01/EML2006Novatchev01.html" rel="nofollow">read more here</a>. In the forthcoming <a href="http://www.w3.org/TR/xpath-30/#id-literal-func-ref" rel="nofollow">XPath 3.0</a> functions are for the first time first class objects in the <a href="http://www.w3.org/TR/xpath-datamodel-30/#function-items" rel="nofollow">Xpath Data Model</a> (XDM).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
