Correct it does not filter, although it could be argued it initializes
in the case that a parameter is not passed in.  It sounds like you get
the basic idea.

Ummm, actually, I believe David Carlisle answered that question a
couple of days ago.  select='/..'.

It's also mentioned in the XSLT 1.0 spec under 11.2 Values of
Variables and Parameters: "One convenient way to specify the empty
node-set as the default value of a parameter is:

<xsl:param name="x" select="/.."/>"

I don't do much with XSLT 2.0 so I'm not sure how the empty-sequence works.
