RE: [xsl] Empty String param

You get the default value of the parameter only if you call the template
with no xsl:with-param element for that parameter. You don't get it if you
supply a parameter and the value of the parameter is an empty sequence. An
empty sequence is treated just like any other value you might supply.

You aren't supplying a zero-length string as the parameter value, you are
supplying an empty sequence.
