[xsl] RE: Variable: true or false

I recently submitted the original message and got the answer that the
variable "selectUser" should be an empty string and that
Xalan was probably getting it wrong.

As a follow on I was wondering what is supposed to happen if I change:

  <xsl:variable name="selectUser"/>
  <xsl:param name="selectUser"/>

I want to determine if a param passed into a stylesheet has been
assigned a value. In a perfect world, should I still be able to do
the simple true/false test? My guess from looking at the spec is
that "selectUser" should be an empty string if it is not assigned,
just like the variable case.

I do the transform on this XSL and get "true". I would have expected
Thought the boolean of an empty object would always be false.

Using Xerces 1.4 and Xalan 1.1

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
   <xsl:variable name="selectUser"/>
   <xsl:template match="/">
         <xsl:when test="$selectUser">
