Slightly tricky one that, even under XSLT 2.0. I came up with

replace($in, '(\S)\s+(\S)', '$1 $2')

but I don't think this works if there are single-character words between the
spaces. Schemes for extracting the leading/trailing whitespace and adding it
back afterwards also have to cater for the possibility that the string is
all-white. 

Perhaps:

<xsl:analyze-string select="$in" regex="^(\s*)(.*?)(\s*)$">
  <xsl:matching-substring>
    <xsl:value-of select="regex-group(1)"/>
    <xsl:value-of select="normalize-space(regex-group(2))"/>
    <xsl:value-of select="regex-group(3)"/>
  </xsl:matching-substring>
</xsl:analyze-string>

Not tested.
