How to create a new empty message from a schema?

| Hello
I have a message based on and xml schema, I would like to instance the message in the orchestration in the assign shape, I would like to create a new message (empty), what should I do, what are the commands to use? I am having a problems with the "new" command.

| Came on, this must be the easiest question ever!
In C# if you would like to instance an object is simply
Object a = new object a();
In BizTalk, I am trying to do that in the message assignment, and it does not work.
Actually, of course it must not work, instancing an object is so complicated, that even BizTalk can't do it, there are even no samples in the SDK (or I can't find one) that does that!

| Create a variable of type xmldom in the orchestration
set this to a new instance of an xmldom in your assign shape.
Load some xml into the dom that matches your schema (essentially, whatever xml you want in your new "empty" schema).
Assign the xmldom to the message you have said you are constructing.
Done.
You can also get a dom from a .net class if you want to have some reusable code that creates that emtpy xml for you.
Keep in mind that when using the xmldom, it has to be within an atomic scope because it is no serializable. for more detail on that, search the group for related posts about serializable errors.

| You can use variable of type System.Xml.XmlDocument to load an xml instance
and then assign that to the message. System.XML.XmlDocument is special
cased specially for this kind of usage and you do need the atomic scope in
this case even though it is not XML Serializable.
