extension naming

Hi, I guess xmlprci is following the mysqli example. I am not sure if this is a good idea to have new BC breaking versions of extensions append letters like "i" (aka "improved") to solve the namespace issue. So I would like to bring this topic up for discussion on this list before too many other extensions blindly follow this example, just because of the lack of a standarized alternative. Anyways I dont really know if anyone from php core cares about these kinds of topics so just tell me to stfu before we get a needless flame. The obvious problem is: What comes after "i"? How transparent is this naming scheme to the user? We had to address a similar problem in PEAR and we currently have the following regulation in place which is a solution which is not beautiful either: http://pear.php.net/group/docs/20031114-bbr.php I guess the only advantage to using letters to denote new major versions is that I dont know anyone else using "i" as a postfix like this. So we are less likely to clash with a theoretically possible xmlrpc2 standard if we were to use the more common method of appending numbers. Also while xmlrpci is only a pecl ext for now is seems like it registers a class called xmlrpc ("REGISTER_XMLRPCI_CLASS(xmlrpc, rpc, NULL, 0)"). I dont think this is a good idea either. regards, Lukas
