Gopal, Simon, I and others were discussing compatibility issues between mono, 
rotor, pnet, and .Net 's  XmlTextReader::Read() method...

Read() in our System.Xml will basically look through a tag ie:
<element attribute="textvalue">textvalue</element>

respectively scans a NodeType per Read() instruction

a testcase ran with 
using System;
using System.IO;
using System.Xml;
public class XmlTest
        public static void Main()
                String data="<tag attr=\"foo\">data</tag>";
                StringReader stream=new StringReader(data);
                XmlTextReader r=new XmlTextReader(stream);

address@hidden tests]$ ilrun a.out.exe 
address@hidden tests]$ mono a.out.exe 
address@hidden tests]

And .NET outputs Nothing ....

Gopal and I have come up with a solution that will turn Read() into ReadNode() 
and then creating a wrapper called Read() that will read up to the '>' per 

This is the only necessary way to enable the XmlTextReader::MoveTo*  methods 
to properly work.  My opinion is that the only thing worth making these 
changes for is the Qt# generator, which is a handbuilt XmlTextReader.  I was 
told it was built with mono's reader in mind, because they have no 
implemented anything that builds a DOM structure at that point in time.  In 
my opinion all these MoveTo* methods are redundant in the ecma standard, but 
it comes down to being ecma compliant at the end of the day.  It will only 
cost us an internal class and another wrapper method inside XmlTextReader.  
What are your thoughts, should we lead the standard and fix redundancy in the 
ECMA spec? I could help out with the generator and make it work with 
XmlDocument since its the same across all implementations AFAIK.  That could 
save us from hurting speed we get from Reader at present.  I've included a 
half working patch that Gopal has sent to me earlier that is up to the latest 

Now it's time for a coffee break.
