[RfC] XML_Serializer, XML_Util

Hi, some more questions on my XML_Serializer package. As this package grows, I think it would be wise to put some common methods, that can be used by other XML_* packages in a new package called XML_Util (name could be changed, of course). This package offers static methods to replace XML entites (<,>,&,',") in a string, to convert an associative array into an attributes string, and to do some other common tasks. These methods are needed by a lot of classes and including them in every package is redundant and produces errors (e.g XML_Transformer_Util::attributesToString does not replace entities in the attribute values, which could produce XML that's not well-formed. So I think supplying one package that does these really simple tasks allows the XML_* package developers to concentrate on the main tasks. Furthermore I'd like to hear your comments on another subject: Should there be two packages: XML_Serializer and XML_Unserializer or if I should include both classes in one package. If you prefer the latter, how should the files be organized? XML/Serializer/Serializer.php and XML/Serializer/Unserializer.php or XML/Serializer.php and XML/Unerializer.php? Waiting for your comments... Stephan
