<xsl:analyze-string regex="{[^{}]*}" select="$lines">

The regex should be written

regex = "[^{{}}]*"

No outer curlies, because this is an AVT attribute, and curlies are used to
enclose XPath expressions.

Similarly the inner curlies must be doubled to stop them being treated as
AVT curlies that introduce XPath expressions.

<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>

Which I'm sure must be wrong because saxon gives me:
----------

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...
