I'm trying to run a in mono for windows and I hit difference in XDocument.Load
behavior between MS and mono frameworks.
Mono gives me an exception if document contains DTD declaration while MS
framework works without complains.

Exception:
================================
Unhandled Exception: System.Xml.XmlException: Document Type Declaration (DTD)
is prohibited in this XML. file:///C:/projects/experimental/
Test/XdocTest/bin/Debug/test.xml Line 2, position 10.

=====================================

Program:
======================================
static void Main(string[] args)
        {
            string test = @"<?xml version=""1.0""?>
<!DOCTYPE opml SYSTEM ""http://dtd.mycompany.com/opml.dtd"">
<opml></opml>";

            var doc = XDocument.Parse(test);
            doc = XDocument.Load(new StringReader(test));
            doc = XDocument.Load("test.xml");
        }
======================================

When loading the same document from string or string reader, it works fine
under Mono, but when calling Load, it fails.
I see in mono source code that XDocument sets s.ProhibitDtd = false when
reading from TextReader but apparently it needs to be set when reading from uri
too in order to replicate MS behavior.
