The problem with this is that 1) is a very hard step to 
accomplish. There is actually std.experimental.xml, but it's not 
complete enough to merge into std. It's much easier to develop a 
non-std XML parser, because you can support only part of 
functionality (read or write XML) and you can ignore rarely used 
features like entities.

As soon as you try to merge anything into std, new requirements 
show up. The library needs to play well with ranges, most people 
would want it to play nicely with @nogc, it would have to support 
both reading and writing and should support most if not all XML 
features.
