The "deficient namespace handling in the stdlib" is only relevant when parsing XML, then trying to re-emit it. Since this library does not support re-emitting XML, it is either "worse" or "n/a", depending on your mood. However, looking at the output data structures, yes, it would have the same problem if the obvious modification to re-emit XML was made. It's actually very common, to the point I'm surprised when I encounter an XML parser that handles the problem you are referring to correctly, in any language. I've had to hack it in to every XML parser I've ever used when I care about preserving namespace abbreviations.
