Add message parameter XML-escaping to <html:messages>

           Summary: Add message parameter XML-escaping to <html:messages>
           Product: Struts
           Version: Nightly Build
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Enhancement
          Priority: Other
         Component: Custom Tags
        AssignedTo: struts-dev@jakarta.apache.org
        ReportedBy: roberto.tyley@reuters.com


This is small enhancement to the <html:messages> tag, adding a boolean attribute
which enables the XML-escaping of message parameters, while leaving the text of
the message pattern itself intact. 

This can be useful if you have markup in your message patterns which you would
like to keep, but want to filter the parameters going into them, e.g. if they
reflect user input:
                  
errors.divideZero=The mathematical expression <strong>{0}</strong> caused a
divide by zero.

Currently, you can escape XML using <bean:write name="error" filter="true"/>,
but this would filter the helpful <strong> tag also. The proposed new feature
would allow for sensible use of html tags in message properties, while still
protecting against abnormal user input.

I've implemented this feature in patch against nightly build
'jakarta-struts-20040113' and will attach the patch shortly.


best regards,

Roberto
