XSLT support for Zope3
======================

Installation
============

In order to use this product, you will have to include the package in
your products.zcml file.

Requirements
============

Currently, this product requires 4Suite 1.0a1 or higher.

Example
=======

Please check out zopeproducts/xslt_example for an example.

Later on we may want to implement a special ZCML directive to set up
an XSLT adapter which converts from one XML schema to another one
using an XSLT style sheets like this:

  <zopexml:xsltadapter
    for="http://xml.zope.org/xml_examples/apple"
    provides="http://xml.zope.org/xml_examples/pear"
    xslt="apple-pear.xsl" />
