[HEADS-UP] Changes to Sitemap's TreeProcessor

[Grzegorz Kossakowski <gr...@tuffmail.com>]

Hello,

I've applied changes in r567057 that were discussed here[1]. Briefly speaking, this change allow us 
to switch to new unified expressions by changing one line of configuration in this[2] file:

   <property name="stringTemplateParser" 
ref="org.apache.cocoon.el.parsing.StringTemplateParser/legacySitemap"/>

If you change it to:

   <property name="stringTemplateParser" 
ref="org.apache.cocoon.el.parsing.StringTemplateParser/default"/>

You will immediately get a possibility to use new expressions in sitemap, like:

   <map:transform type="xslt" src="style.xsl">
     <!-- here we assume that default EL is JXPath -->
     <map:parameters name="param1" value="{$cocoon/request/parameters/param1}"/>
   </map:transform>

While that is neat it could introduce very unexpected problems and bugs. I've touched very core 
functionality of TreeProcessor and it was first, brave attempt to introduce Spring to TreeProcessor. :-)

I tested my changes and everything seems to work as before but I don't understand all constructs in 
TreeProcessor so some obscure problems may arise.

Please test new changes with your applications and report problems so we can fix them ASAP.
