JAXP - 'DOMImplementation' instance

[Stanimir Stamenkov]

Is there any reason for the 'getDOMImplementation()' method to be
part of the 'DocumentBuilder' interface and not part of the
'DocumentBuilderFactory' one? Does the returned 'DOMImplementation'
instance differ (or would it differ) depending on the configuration
(namespace awareness, validation, etc.) used to create the builder?

Maybe in theory there could be a difference, for instance if you do not
need namespace awareness then a DOM Level 1 compliant implementation
would suffice while for namespace aware DOM manipulation at least DOM
Level 2 is needed.
