May be that sentence could be refined. But I wholeheartedly subscribe 
to the spirit of it. Feel free to explain why that is a sign of

Well, there is some truth to the claim that HTML-compatible XHTML can 
overcome difficulties in incompliant HTML-consumers.

Is there a concrete reason to mention libxml2? 

If I could wish for things, then I think <meta http-equiv=Content-Type 
content="text/html;charset=UTF-8"/> should be permitted in XHTML5, - 
and not only <meta charset="UTF-8"/>. That would increase the 
capability of legacy content producers to create more or less polyglot 
markup. May be I should file a bug?

The result is polyglot. So one could ask why shouldn't one label it so? 
But of course we could bikeshed about another name.
