Ahhh, right! I didn't even see that the <xsl:param> declaration was missing
(this was based on a user's bug report).

Still, libxslt behaves the same, even when I add the <xsl:param> declarations.
So, this leaves us with two problems that should raise an error:

- accessing an undeclared variable (e.g. xsl:value-of w/o xsl:param/variable)

- passing an invalid (i.e. non-evaluatable) value as a parameter
