Cause i have the following structure
<template name="list-item">
<param name="context">
<li>
<apply-template select=".">
<with-param name="context" select="$context"/>
<apply-template/>
</li>
</template>
<template match="specific-item1">
<param name="context">default value</param>
[..]
</template>
When calling list-item template with a context parameter, it get forwarded to
template specific-item1. But when calling list-item template without this
parameter, it forwards an empty context parameter to template specific-item1,
thus preventing default value use :-(
