Maybe we should have a go at obfuscating XSLT through over zealous use

<!ENTITY opt '<xsl:output indent="yes"/>'>
<!ENTITY ident '<xsl:template

Since entities resolve recursively, this cries out for more:
<!DOCTYPE xsl:stylesheet [
<!ENTITY xslt-ns 'http://www.w3.org/1999/XSL/Transform'>
<!ENTITY all '@*|node()'>
<!ENTITY opt '<xsl:output indent="yes"/>'>
<!ENTITY copy '<xsl:copy><xsl:apply-templates
select="&all"/></xsl:copy>'>
<!ENTITY ident '<xsl:template
match="&all;">©</xsl:template>'>
]>
<xsl:stylesheet xmlns:xsl="&xslt-ns;"
version="2.0">
&opt;
&ident;
</xsl:stylesheet>
