No it doesn't. XML is either well formed or not, and any parser encountering non well-formed XML will reject it outright.

Therefor all XML in use on the internet is spec-compliant.

Now try to say the same about JSON.

Ah, I see you're new to parsing XML.

[Aeolun]

Oh, it will be rejected alright. And then you're forced to override the parser, or to manipulate the XML before parsing it because it makes business sense to not have the source fix their XML for some reason.

People and machines are just utterly incapable of outputting valid XML.
