It seems reasonable that the feature be mandatory, (so long as you don't
mandate that all SAX parsers accept a value of "true", as some just won't
have the ability to read network resources). I'm not sure how existing
applications would be affected if the default value was mandated rather than
being unspecified as it is at present.
The process for suggesting this kind of change to SAX involves raising an
RFE on the sourceforge site [1].
