When I asked the tomcat mailing list for Zope like functionality in tomcat
(some year ago) nobody even answered. The product probably wasn't known or
nobody saw the possibilities. I still think cocoon rocks, and
session managament in Tomcat is way better than in Zope. The problem is
that Tomcat demands more skills from the webbies. and Zope allows easy
maintainance of 'live' sites, on site. Anyway,

Having moved ZZICT towards zope from jsp. we faced the same XSL/XSLT
problems. I often wondered: how come they have xml-rpc but not XSLT?

We developed more or less the same thingy: a ZZXML product which is an XML
file which upon rendering can be transformed by any number of XSLTs. the
way the XML and XSL are linked is that of the XSLT spec:
<?xml version = "1.0"?>
<?xml-stylesheet href="....xsl" type="text/xml"?>
I personally hacked in into a Zope 2.4 with the python xml.xslt and
xml.dom.ext packages and some 200 lines of glue code.
The problems with the thingy are:
- xml authoring :the xml documents are only editable as text
- xslt is not context sensitive. fi I'd like to be able to apply different
style sheets for (fe) different authorization roles
- for some reason the webbies don't really like an XML/XSLT pipeline,
because it is rather difficult to get the separation of concerns right.
(fe content:XML only, first style sheet: structure of page second style
sheet: markup elements , third style sheet: browser specifics aso)
Web publishing still remains rather hard.

In short: yes, donno, yes.
