    Summary: DOMConfiguration param. from getParameterNames() not recognized by getParameter
       Type: Bug

     Status: Open
   Priority: Minor

    Project: Xerces2-J
 Components: 
             DOM
   Fix Fors:
             2.6.2
   Versions:

Description:
all getParameterNames to get a list of parameter names known to the
DOM implementation.  Call getParameter( name ) to get the current setting
of each supposedly known parameter.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
getParameter should never reject a parameter name from getParameterNames
as unknown (or getParameterNames should never return an unknown
parameter).

ACTUAL -
(See exact error below.)

getParameter throws a FEATURE_NOT_FOUND DOMException, saying it
doesn't recognize the feature name even though the feature name came
right from the DOM implementation.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
org.w3c.dom.DOMException: FEATURE_NOT_FOUND: The parameter 
http://xml.org/sax/features/validation is not recognized.
	at com.sun.org.apache.xerces.internal.dom.DOMConfigurationImpl.getParameter(DOM
ConfigurationImpl.java:863)
	at prototype.ExploreDOM.main(Bug.java:29)
Exception in thread "main"


REPRODUCIBILITY :
This bug can be reproduced always.
