That's not necessarily the case. XSL:P, the default processor in
cocoon-1.5, supported an early working draft of the XSLT spec. Xalan, the
default in 1.6, supports the final draft of the XSLT spec. Things did
change between the two, though not a _huge_ number of things. The main
difference is that Xalan is more picky (and correct) than XSL:P.

Your XSLT stylesheet _must_ be well-formed XML, therefore the non-XSLT
tags inside it must be well-formed XML. <br>'s must be written as <br/>,
<html> must be balanced by </html>, etc. AFAIK, it _is_ possible to create
non-XML output, but you must do so by creating literal result elements
using xsl:element. What you oughta do is download a copy of tidy and run
it against your stylesheets (tidy -e -xml foo.xsl).
