comment-escape-string — Prepare a string for inclusion in an XML comment

## Description

The `comment-escape-string` template returns a string that has been transformed so that it can safely be output as an XML comment. Internal occurrences of "--" will be replaced with "- -" and a leading and/or trailing space will be added to the string, if necessary.

    <xsl:template name="comment-escape-string">
      <xsl:param name="string" select="''"></xsl:param>

      <xsl:if test="starts-with($string, '-')">
        <xsl:text> </xsl:text>
      </xsl:if>

      <xsl:call-template name="comment-escape-string.recursive">
        <xsl:with-param name="string" select="$string"></xsl:with-param>
      </xsl:call-template>

      <xsl:if test="substring($string, string-length($string), 1) = '-'">
        <xsl:text> </xsl:text>
      </xsl:if>
    </xsl:template>
