No it would have no effect at all on the input you posted,
strip space ignores white space nodes used for indentation
so
<Calculation>
  <x>aaa</x>
  <b>bbb</b>
</Calculation>

would be treated like <Calculation><x>aaa</x><b>bbb</b></Calculation>

But you have
<Calculation>
  <![CDATA[zzzz]]>
</Calculation>


which is reported to XSLT as

<Calculation>
  zzzz
</Calculation>

so strip-space has no effect, as there are no text nodes consisting just
of white space.
