A processor that checks an XML document against Javax.Xml.Validation.Schema.

A validator is a thread-unsafe and non-reentrant object. In other words, it is the application's responsibility to make sure that one Javax.Xml.Validation.Validator object is not used from more than one thread at any given time, and while the validate method is invoked, applications may not recursively call the validate method.

Note that while the Validator.Validate(Javax.Xml.Transform.ISource) and Validator.Validate(Javax.Xml.Transform.ISource, Javax.Xml.Transform.IResult) methods take a Javax.Xml.Transform.ISource instance, the Source instance must be a SAXSource, DOMSource, StAXSource or StreamSource.
