Lot of its features are untested at the moment, unittests and other testcases are being written at the moment.
SDL-style datetime parsing have not been implemented yet.
KDL parsing/compatibility might be dropped, not implemented yet due to some of its special.
DOM and its related API will likely stay the same, but with more features added and things refined.
XDL specifications are not 100% finalized, and some features might get added/modified.
It has a mostly working DOM reader and writer in newsdlang.dom, and a more manual streaming parser in newsdlang.parser if someone wants to directly convert *DL files to data without the DOM overhead.
