You'll have to think upsidedown (don't know if this is the right word
for this, but...), i.e., istead of setting the variable inside the
condition, do the test inside the variable.

<xsl:variable name="nextparent">
 <xsl:choose>
  <xsl:when test="substring-after(.,' ')=''">
  <xsl:value-of select="parent::GROUP/@CategoryOrGroupParent"/>
  </xsl:when>
  <xsl:otherwise>
  <xsl:value-of select="concat(substring-after(.,' '),' ',$ROOT)"/>
  </xsl:otherwise>
 </xsl:choose>
</xsl:variable>

Hope this helps
