RE: Problem with conditional definition of a variable

You can fill the blanks with the <xsl:value-of> to assign a value to the
variable or <xsl:sequence> to assign a result of a XPath expression to
the variable.

Subject:  Problem with conditional definition of a variable

Depending on whether or not a parameter is passed to the stylesheet, I'd
like to define a variable differently.

I have defined two parameters in the stylesheet to be passed from a
command line:

"spiral" has a default value.
"phase" is defined without a default value.

This unconditional definition works as expected:

<xsl:variable name="s1-reqs" select="document('X:/Project
documents/matrix-xml/spiral-phase-update-template.xml')/requirements/req
uirement[@spiral=$spiral]" />

I think I ought to be able to declare the variable with a construct like
this:

<xsl:variable name="s1-reqs">
  <xsl:choose>
    <xsl:when test="$phase=''">
      <!-- Something goes here when no "phase" parameter is passed -->
    </xsl:when>
    <xsl:otherwise>
      <!-- Something goes here if a "phase" parameter is passed -->
    </xsl:otherwise>
  <xsl:choose>
</xsl:variable>

but I must have the wrong idea because I can't find a way to fill in the
blanks. If someone sees where I'm going astray, please clear this up for
me.

Thanks.
