I get:
------------
<xsl:template match="l/text()">
<xsl:variable name="lines">
<xsl:apply-templates mode="a" />
</xsl:variable>
<xsl:analyze-string regex="{[^{}]*}" select="$lines">
<xsl:matching-substring>
<w><xsl:analyze-string regex="{([a-z]*) ([^{}])*}">
                <xsl:matching-substring>
                <xsl:element name="{regex-group(1)}">
                 <xsl:value-of select="regex-group(2)"/>
                </xsl:element>
                </xsl:matching-substring>
        <xsl:non-matching-substring>
        <xsl:value-of select="."/>
        </xsl:non-matching-substring>
</xsl:analyze-string></w></xsl:matching-substring>
<xsl:non-matching-substring><xsl:value-of select="."/></xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:template>

Which I'm sure must be wrong because saxon gives me:
----------
saxon -o temp2.xml temp.xml addwords2.xsl

Which I'm sure I've created by not adding the regex properly
in the word regex.  Should that be {\w+[^{}]*}  or something?

I've always had a difficult time with regular expressions...
