What do you want to test :
1. CalcRows existing in the current context node ?(ex: 
<foo><CalcRows/></foo>

2. CalcRows having some text value ?(ex: <CalcRows>some text</CalcRows>)
3. CalcRows having children ? (ex: <CalcRows><foo/></CalcRows>
4. CaclRows having children with text value ? (ex: <CalcRows><foo>some 
text</foo></CalcRows>

for 1 it would be :
<xsl:when test="CalcRows">

for 2 it would be :
<xsl:when test="CalcRows/text()">

for 3 :
<xsl:when test="count(CalcRows/*) &gt; 0">

for 4 :
<xsl:when test="CalcRows/*/text()">
