+Summary: XML WebServices in mono don't expose correctly Nullables so as to be consumed by proxies
+Am going to paste the description posted here[1]:
+Trying to test a mono web service with simple method like this:
+[WebMethod(Description="Test nullables")]
+public int? GetNull()
+    return null;
+Here is output from the latest mono + mod_mono using xsp2:
+<?xml version="1.0" encoding="utf-8"?>
+<int d1p1:nil="true"
+      xmlns:d1p1="http://www.w3.org/2001/XMLSchema-instance"
+      xmlns="http://localhost/webservice/WebService.asmx"/>
+And here is what I've got from IIS and ASP.NET 2.0:
+<?xml version="1.0" encoding="utf-8" ?>
+  <int xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
+    xsi:nil="true"
+      xmlns="http://localhost/webservice/WebService.asmx" />
+Result is that in VS 2005 web reference this method has plain Int32
+result value type instead of nullable Int32.
+They are equivalent in XML sense, but wsld.exe from microsoft's SDK
+generate different C# proxies for GetNull method:
+when web service is running under ASP.NET:
+public System.Nullable<int> GetNull()
+and running under xsp2:
+public int GetNull()
+Mono's wsdl2 tool generates the same result with the
+service running on xsp2:
+public int GetNull()
