  ===================================================================
  
  
  The XMLForm framework is inspired by Apache Jakarta Struts and W3C XForms. 
  Its goal is to:
  
  * Ease the development of sophisticated web applications utilizing complex data types and
multi-page transactions
  * Provide an automated 2 way mapping between HTML Forms <-> XML <-> JavaBeans
  * Use standard XML validation languages like XML Schema, Relax-NG, Schematron for data validation
  * Promote natural reuse of validation, binding and business logic between cocoon actions
(which are best utilized for interactive clients driven web applications ) and web services
(which are in turn becoming the standard machine-to-machine web technology)
  * In doing so, utilize as much as possible of the existing cocoon 2 technology. More specifically:
actions, action sets, cocoon-action parameters and transformers.
  * Utilize existing XPath tools like JXPath for read/write access to JavaBeans, DOM nodes
and mixed
  objects.
  
  
  --------------------------------------------------------------------------------------------
  
  The current implementation offers the following features:
  
  1) Automated 2 way binding of HTML Forms to JavaBeans (and DOM nodes) through XPath
  2) Automatic validation of JavaBeans(and DOM nodes) through Schematron schemas
  3) Intermediate XForms like XML markup for form views

  Following is a summary provided by Daniel Fagerstrom <daniel.fagerstrom@swipnet.se>
  
  
  Background
  ----------
  
  The aim of XMLForm, is to build and edit an xml document (called the
  instance), subject to constraints from some schema (XMLSchema, Schematron,
  ...), through a sequence of form pages. The instance is either a
  dom-document or a Java bean-structure or a mix. XMLForm consist, of
  three main components:
  
  * Form - is responsible for the instance and validation of it. Form objects
  are stored in request attributes for one page forms and session attributes
  for wizards (multi page forms). A Form can be populated from the request
  parameters. This is the "model in MVC terms.
  
  * XMLFormTransformer - takes a form descriptor, (similar to XForms) as input
  and  fill it with data and error messages from a Form object that is
  referred in an attribute. This is the "view" in MVC terms.
  
  * AbstractXMLFormAction, (WizardAction) - creates the Form object if
  necessary and populates it with data based on the request parameters. It can
  also take care of flow handling and checkbox state. This is the "controller" in MVC terms.

  Subject: [Announcement] Cocoon Form Handling - XML Form Release 0.8
  
  
  First, I would like to thank everyone who participates in the Form Handling discussion.
  I have learned a lot from this discussion in the last few weeks.
  
  There are plenty of great ideas coming from all directions, and some of them influenced
my
  thinking significantly.
  
  As I have already mention more than once, I have a certain fear that this topic may be too
large 
  to handle at once and may eventually wind up as it did several times before (Schemox, ExFormular,
etc.)
  I would very much like this time Cocoon to end up with a better overall form handling solution,
than the one that currently exists. It does not have to be perfect from the start.
  
  With all tha said, I am presenting to anyone interested the new incarnation of the xmlform
solution.
  It has gone through major refactoring based on heavy influence from Torsten and Konstantin.
  I will not advertsise what it is this time. I would instead encourage people who are *really*
interested
  in bettering Cocoon, to look at the demo and provided feedback.
  This time there is only one demo, which is an extension of the survey wizard, originally
offered by Torsten.
  
  Once you build c2 with scratchpad, point to 
  http://localhost:8080/cocoon/mount/xmlform/wizard.html
  
  
  For those who will take the time to peek in,
  
  I would like to request votes on the following:
  
  1) Does this solution prohibit further extensions in directions that you might be interested?
  
  2) Does this solution offer better overall form handling than the existing one for C2?
  
  3) Can this solution be the base for 2.1?
  
  
  Thanks everyone,
  
  Ivelin

  Subject: [Announcement] HTML Form binding and validation arrived
  
  ===============================================================
  ! The HTML Form symmetry loop is closed: !
  ===============================================================
  HTML Forms <-> XPath <-> JavaBeans <-> XML -> Schematron -> HTML
Forms
  ===============================================================
  
  Just released the next version of the symmetric Form binding and validation
  toolkit ( a CocoonBlock wannabe :).
  In addition to the form-binding it now has integrated Schematron validation
  support.
  
  The zip file can be downloaded from:
  http://prdownloads.sourceforge.net/freebuilder/CocoonForm_0-6.zip
  
  With this in place one can provide form binding with just a few lines of
  code (~5 lines) and Sophisticated form validation with 0! lines of Java
  code.

  Subject: [Announcement] Fast Schematron Validation Here !
  
  
  
  We've got the rainbow !
  
  +===========================================+
  +    *Fast* Java API for Schematron Validation *Ready* !      +
  +===========================================+
  +    Validates both JavaBeans and DOM nodes                       +
  +===========================================+
  
  It's been another long and fruitful Saturday here in Austin...
  
  I am grateful to everyone in the Cocoon community as well as Dmitri
  Plotnikov for his help with JXPath, Rick Jelliffe for his guidance with
  Schematron and Oliver Becker for the clarifications on his XSLT based Java
  API for Schematron.
  
  
  As I mentioned already, I've decided to implement Schematron in Java using
  JXPath.
  The result is surprisingly little code (~1K lines) and quite exciting speed
  (~20ms per validation for the demo setup).
  
  What's more:
     - Does not need Castor mapping
     - Does not do XSL transformation
     - Direct access through the JXPath library
  
  * Someone let me know if this can be implemented too much faster *
  
  I hope this answers some outstanding questions like:
  "How do we validate HTML Forms ?"
  "How do we reuse validation rules and code for HTML Forms, Web Services and
  domain validation ?"
  "What language do we use or build to implement validation?"
  
  I am not sure if the credits should all go to Schematron or more to XPath,
  but
  Schematron being so simple and powerful is clearly my choice:
  - Schemas can grow organicly. One can start with a few simple rules and grow
  the document with time.
  - Native support for validation in "phases". Unlike XML Schema, one doesn't
  need to provide a complete document in order to be able to perform
  validation.
  - Pin-points the bad elements and provides user-friendly reporting.
  - Very, very simple to learn if one knows XPath. (I just can stop repeating
  that.)
