BasicParserCofiguration recognizes "validation" feature

[Neeraj Bajaj <Ne...@Sun.COM>]

BasicParserConfiguration recognizes "validation" feature, IMO it should not 
recognize "validation" feature as this class is supposed to be reusable as much 
as possible, and different applications are encouraged to write their custom 
configuration using it as base class. There are quite number of applications 
running which dont require validation. Xerces2 also have 
"NonValidatingConfiguration" for any application willing to use Xerces2 in 
non-validating mode.
	In Xerces2, all the configurations extend BasicParserConfiguration, as a 
result this feature is also recognized by each configuration including 
"NonValidatingConfiguration" which should not be the case, as this configuration 
is not capable of validating the instance document against grammar.
	The "validation" feature should be recognized by "DTDConfiguration", so 
it also will be recognized by "StandardParserConfiguration" as it extends above.

Recognizing the value and using it are different things. 
And I think most applications assume that "validation" and
"namespaces" will always be accepted. So removing this
default from the base parser configuration could lead to
problems with lots of apps that make the above assumption.
