I just got a response from one of libxml2's maintainers.
It seems that the docstring for `libxml-parse-html-region' is wrong:
this argument has never served the purpose of resolving relative URLs.
It was only used for error messages. So I suggest that we modify the
docstring of this function and `libxml-parse-xml-region' to reflect this
fact.
I also don't know if, based on this new information, you want to mark
this parameter obsolete. I see no immediate need, though.
Should I send a patch for the documentation change, or will you do it?
