Hi Ken,
  Thanks for pointing the mistake. Below is the modified XSLT 2.0
solution, which works..

<?xml version="1.0"?>
<xsl:stylesheet  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">

 <xsl:output method="text" />

 <xsl:template match="/">
   <xsl:variable name="result">
     <xsl:analyze-string
            select="SomeTag"
            regex="[A-Z][a-z]*">

         <xsl:matching-substring>
           <xsl:value-of select="." /><xsl:text> </xsl:text>
         </xsl:matching-substring>
         <xsl:non-matching-substring>
           <xsl:value-of select="." /><xsl:text> </xsl:text>
         </xsl:non-matching-substring>
     </xsl:analyze-string>
   </xsl:variable>
   <xsl:value-of select="normalize-space($result)" />
 </xsl:template>

</xsl:stylesheet>

Though your solution is very concise, and I myself would prefer that.
