I type the following command:
nxslt2.exe MyXml.xml stylesheet.xsl -o output.xml -ext ClassLibrary1.MyClass -af ClassLibrary1.dll xmlns:ExtHelper="ClassLibrary1.MyClass"

NOTE: ClassLibrary1.dll is found is in the same directory as nxslt2.exe

I get the following error:
An error occurred while instantiating 'ClassLibrary1.MyClass' type: Extension object 'ClassLibrary1.
MyClass' must be bound to a namespace URI.

Where do I need to bind the Extension Object to a namespace URI? and how do I do it?

Thanks,
