Unless the implementation understands xhtml / html - http://bar.com/ that's an interpretation on top of the original XML view > 3. http://bar.com/ Wrong, the base applies only to the element carrying the xml:base and below. If you ask for the *document base* the document node is an ancestor of Foo and the answer is still the original URI > 4. http://bar.com/ xmlCheckHTTPInput does this, it's called by xmlNewInputFromFile() in libxml2 it is possible it may be missing in some case, or the PHP I/O architecture doesn't do something similar. > 5. http://foo.com/ Wrong, same misunderstanding as 3/ > > The current behavior for PHP (using libxml2 2.6.31) isn't that. I can't tell for PHP, but at least 2 of your expectations are clearly wrong from purely a spec perspective.
