There's a discussion going on regarding how to get raw string content from HTTP requests; LzDataset is not really set up to do that. I just recently remodularized the LzHTTPLoader API to properly support raw dataresponses, as part of the XMLRPC updates (so we could get JSON responses), so it seems like it would be a good time to figure out how we let developers in LZX get raw string data responses for HTTP requests.

So, no XML-Parser will accept HTML-Code.
