I am trying to parse an HTML document with the doctype declared to use
the transitional dtd as follows:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
When I do Builder.build on the document, I get the following exception:
java.io.IOException: Server returned HTTP response code: 503 for URL: http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1305)

If I remove the doc type declaration, it parses just fine. I can
successfully download the dtd from my browser, which tells me that the
url is valid. I don't want to remove the doc type declaration. Is
there a way tell the builder not to download the dtd or provide it
with an alternate dtd?
