There are two binding files included in the ESB toolkit 2.1 that are made available if you want to make changes to the bindings.

WARNING: DON”T MODIFY THE BINDING FILES WITH AN INTELLIGENT XML MODIFICATION TOOL (like Visual Studio)

You will make the modifications, import the binding file, and it will import it correctly, and when you go to start the Microsoft.Practices.ESB, you will get this error:

The issue is that it changes the filter from:

<Filter>&lt;?xml version="1.0" encoding="utf-16"?&gt;
	&lt;Filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt;
	&lt;Group&gt;
	&lt;Statement Property="ErrorReport.FailureCode" Operator="6" /&gt;
	&lt;/Group&gt;
	&lt;Group&gt;
	&lt;Statement Property="Microsoft.Practices.ESB.ExceptionHandling.Schemas.Property.FaultCode" Operator="6" /&gt;
	&lt;/Group&gt;
	&lt;/Filter&gt;</Filter>

to

<Filter>
        &lt;?xml version="1.0" encoding="utf-16"?&gt;
	&lt;Filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt;
	&lt;Group&gt;
	&lt;Statement Property="ErrorReport.FailureCode" Operator="6" /&gt;
	&lt;/Group&gt;
	&lt;Group&gt;
	&lt;Statement Property="Microsoft.Practices.ESB.ExceptionHandling.Schemas.Property.FaultCode" Operator="6" /&gt;
	&lt;/Group&gt;
	&lt;/Filter&gt;
</Filter>

Lesson to learn: the filter settings within the binding file need to be correctly formatted xml (spaces before the first open carrot is illegal)
