Sean Gilligan writes about a [known] problem with
<xsl:copy-of select="document('')/xsl:stylesheet/namespace::exsl"/>
One possible workaround that may be pretty universal is to try
<xsl:copy-of
select="document('')/xsl:stylesheet/namespace::*[name(.)='exsl']"/>
or maybe even try local-name(.) if desperate. Use string(.) to match the
namespace URI.
