std.xml2 (collecting features)

[Robert burner Schadek via Digitalmars-d]

std.xml has been considered not up to specs nearly 3 years now. 
Time to build a successor. I currently plan the following featues 
for it:

- SAX and DOM parser
- in-situ / slicing parsing when possible (forward range?)
- compile time switch (CTS) for lazy attribute parsing
- CTS for encoding (ubyte(ASCII), char(utf8), ... )
- CTS for input validating
- performance

Not much code yet, I'm currently building the performance test 
suite https://github.com/burner/std.xml2

Please post you feature requests, and please keep the posts DRY 
and on topic.
