Glad that we agree the kernel doesn't need any XSLT conditional instruction.

In a previous message you mentioned that  "Unfortunately, XSLT does
not have a notion of polymorphism".

This isn't exactly true.  Polymorphism is implemented in the XSLT
processing model based on the concept of applying templates.

While the body of an <xsl:if> or <xsl:when> or <xsl:otherwise> is
hardcoded and known, when we write <xsl:apply-templates> we don't know
what template will be selected for execution and what its body will
contain. Indeed this template may be written years after we wrote the
<xsl:apply-templates>. This is quite similar to virtual methods in OOP
and has the same effect. This is how XSLT implements polymorphism.
