[patch][woody]  Making WoodyTemplateTransformer Flow-aware.

           Summary: [patch][woody]  Making WoodyTemplateTransformer Flow-
                    aware.
           Product: Cocoon 2
           Version: Current CVS 2.1
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: general components
        AssignedTo: dev@cocoon.apache.org
        ReportedBy: mpo@apache.org


This patch allows
1/ to have the form/@action dynamically set to a jxpath evalutaion 
   of the form #{$continuation/id}
2/ to look for the form instance in the flow context model
--
This introduces a jxpath context member in the template transformer that is used
for evaluating #{--jxpath-expression--} in the text of a wt:form-template tag

Typical usage is in updating your existing woody-templates to hold this tag:
<wt:form-template method="POST" action="#{$continuation/id}.kont">
--
This also lowers the required 'form-attribute' parameter to be an optional
parameter. If it is not set then the flow-context-object will be considered
being a java.util.Map that holds the form instance under the 'woody-form' key
--
Finally this holds some comments/suggestion about how we could extend this 
even one step further to actually support multiple woody-forms on one page.
We could allow for multiple wt:form-template tags on one page that each declare
themselves the form-lookup key in the flow-context-object-HashMap using their 
own specific @location="#{/woody-form}"
