Keyword null in AutoIt

[dwerf]

How can I write this VBScript in AutoIt?

set SchemaCache = CreateObject("Msxml2.XMLSchemaCache")
SchemaCache.Add "", null

I've tried 0, '0', '', 'null', Chr(0) and a not initialized variable instead of null.

An error occures: "The requested action with this object has failed."

$SchemaCache = ObjCreate("Msxml2.XMLSchemaCache")
$SchemaCache.Add("", '')
