std.xml2 (collecting features)

[Dejan Lekic via Digitalmars-d]

If you really want to be serious about the XML package, then I 
humbly believe implementing the commonly-known DOM interfaces is 
a must. Luckily there is IDL available for it: 
https://www.w3.org/TR/DOM-Level-2-Core/idl/dom.idl . Also, 
speaking about DOM, all levels need to be supported!

Also, I would recommend borrowing the Tango's XML pull parser as 
it is blazingly fast.

Finally, perhaps integration with signal/slot module should 
perhaps be considered as well.
