+The SDL now uses the namespace "homegatewayinitiative.org" as a namespace to identify the schema (also used for includes). The namespace is **not** a URL, but uniquely identifies the namespace and *should* be registered by HGI.
+
+That said, most validating parsers expect **that the namesapce IS a valid URL** or that at least there is a server on the other end rejecting the request. A timeout / no connection / no answer / ... leads to an error.
+
+Therefore, we cannot use the namespace "homegateway.org" because parsers don't get an answer from this address.
