In fact, I really think we should remove the methods that build from an
InputStream, File, and URL from DOMBuilder. This will reduce the chances
that people will use DOMBuilder instead of SAXBuilder. I can imagine
people not reading the doc carefully, and then get discouraged because
it's so slow. The methods say that they're useful for debugging - does
this mean for debugging the DOMBuilder implementation? If so, they
really don't belong in the public API. (If someone really needs to do
this, for some reason, they can always use JAXP to parse the file into a
DOM tree theirself, and then use DOMBuilder on that.)
