Xml schema validating parser
It will only contain log entries that appeared during the validation.
Similar to XSLT, there's also a less efficient but easier shortcut method to do one-shot Relax NG validation: lxml.etree also has XML Schema (XSD) support, using the class lxml.etree. The API is very similar to the Relax NG and DTD classes.
To report errors, it is necessary to provide an Error Handler to the underlying implementation.
XSD files are "XML Schemas" that describe the structure of a XML document.
