Use W3C XSD schema to validate the document as it is processed. Activation is only possible before the first Read().
The filename of the XSD schema.
Връща TRUE при успех или FALSE при неуспех.
Issues E_WARNING if libxml was built without schema support, the schema contains errors or if XMLReader::read() has already been called.
Тази функция е налична единствено, когато PHP е компилиран с libxml 20620 или по-късна.
