Maybe I have found a solution. It works, at least with libxslt.
is this correct? I think is is rather a hack.

<!--Select the first paragraph of all chapters-->
<xsl:template match="//chapter/section[1]/para[1]" priority="1">
	<xsl:call-template name="first_line">
		<xsl:with-param name="string" select="."/>
	</xsl:call-template>
</xsl:template>



<!--Select all other paragraphs-->
<xsl:template match="//para">
	<xsl:call-template name="para.template">
	</xsl:call-template>
</xsl:template>



<xsl:template name="first_line">
<xsl:param name="string"/>
<xsl:param name="string2"/>
<xsl:param name="string3"/>
<xsl:choose>

<!--are there any spaces???-->
<xsl:when test="contains($string, ' ')">
<div>
<b>
<!--1st word-->
<xsl:value-of select="substring-before($string,' ')"/>
<!--give back the space-->
<xsl:text> </xsl:text>

<!--2nd word-->
<xsl:value-of select="substring-before( substring-after ($string, ' '), ' ')"/>
<!--give back the space-->
<xsl:text> </xsl:text>

<!--3rd word-->
<xsl:value-of select="substring-before( substring-after ( substring-after ($string, ' '), ' '),' ')"/>
<!--give back the space-->
<xsl:text> </xsl:text>
</b>
</div>
</xsl:when>


			<xsl:otherwise>
				<xsl:call-template name="para.template">
				</xsl:call-template>
			</xsl:otherwise>

  </xsl:choose>
</xsl:template>

Hmmm... just after posting, I realized it's probably safer to use "normalize-space(.)", to ignore any leading whitespace:

<xsl:param name="split" select="3"/>
<xsl:template match="para">
<para><xsl:call-template name="splitwords"/></para>
</xsl:template>
<xsl:template name="splitwords">
<xsl:param name="i" select="0"/>
<xsl:param name="str1" select="''"/>
<xsl:param name="str2" select="normalize-space(.)"/>
