Yes, I thought of that, but I don't think that it works. Say you did:

  <xsl:analyze-string select="." regex="(\W|^)(foo|bar)(\W|$)">
      <xsl:value-of select="regex-group(1)" />
      <special><xsl:value-of select="regex-group(2)" /></special>
      <xsl:value-of select="regex-group(3)" />
      <xsl:value-of select="." />

with the string 'foo bar'. The first matching substring is "foo ".
This leaves the string "bar", but the ^ only matches at the actual
start of the string, not at the start of the
substring-that's-left-after-the-last-match, so it doesn't recognise
the word 'bar'.

Perhaps you need to do non-whole-word processing and then post-process
the result to find the <special> elements that are either first/last
or are immediately preceded/followed by a text node whose last/first
character is a non-word character...
