If you did want to use a  key then all you need to do is define the key:

<xsl:key name="conn-by-source" match="connection" use="@source"/>

then put this wherever you want your output:

<xsl:text>event.0</xsl:text>
<xsl:apply-templates select="key('conn-by-source', 'event.0')"/>

and have this template:

<xsl:template match="connection">
	<xsl:text> -> </xsl:text>
	<xsl:value-of select="@destination"/>
	<xsl:apply-templates select="key('conn-by-source', @destination)"/>
</xsl:template>

and thats it - no need for recursive named templates: the "recursion"
stops when the key doesn't return an element for a given string.
