Thanks Michael. I was looking at http://json.org and here's what I came up

    <xsl:template match="text()" mode="json-identity">
select="replace(replace(replace(replace(replace(replace(., '\\',
'\\\\'), '''', '\\'''), '&quot;', '\\&quot;'), '&#09;', '\\t'),
'&#10;', '\\n'), '&#13;', '\\r')"/>

Can this be improved?
