By default libxml2 XML parser does not fetch the external subset of DTDs. So the undeclared entities are an error but not a fatal error (since of course they never set standalone="yes"). The fact they are invalid doesn't bother me that much, but it seems in practice they are often not well-formed and a lot of RSS readers don't use XML parsers to work around this. One thing is sure, I won't encourage this trend...
