Description:
------------
I experienced it using XMLReader, I don't know if it affects other tools too:

Even if I set XMLReader to validate XML document against RelaxNG or XSD schema, then libxml_get_errors() will obtain an error:
Validation failed: no DTD found!

Reproduce code:
---------------
libxml_use_internal_errors(true);

$XMLReader = new XMLReader;
$XMLReader->open('./path/to/file.xml');
$XMLReader->setRelaxNGSchema('./path/to/schema');
$XMLReader->setParserProperty(XMLReader::VALIDATE, true);

do
{
	$element = @XMLReader->read();
} while ($element);

var_dump(libxml_get_errors());

Expected result:
----------------
array(0) {
}

Actual result:
--------------
array(1) {
  [0]=>
  object(LibXMLError)#2 (6) {
    ["level"]=>
    int(X)
    ["code"]=>
    int(X)
    ["column"]=>
    int(X)
    ["message"]=>
    string(33) "Validation failed: no DTD found !"
    ["file"]=>
    string(X) "./path/to/file.xml"
    ["line"]=>
    int(X)
  }
}

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.
