[PATCH] (XPath)TraversableGenerator improvements

           Summary: [PATCH] (XPath)TraversableGenerator improvements
           Product: Cocoon 2
           Version: Current CVS 2.1
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: sitemap components
        AssignedTo: dev@cocoon.apache.org
        ReportedBy: unico@hippo.nl
                CC: arje@hippo.nl


The discussion about this patch took place on the cocoon dev list and can be
found here:

http://marc.theaimsgroup.com/?l=xml-cocoon-dev&m=106510328905939&w=2

To summerize:
- allow non-collection resources to be input source
- check whether input source exists
- query Context object mime-type mapping when deciding whether to execute the
xpath in XPathTraversableGenerator.
