Remarks
The XmlReader class can enforce validation using a schema or document type definition (DTD). The ValidationType enumeration specifies the type of validation the created XmlReader instance should perform. The XmlReader instance can be either a validating XmlReader object created by the Create method, or an XmlValidatingReader object.
The validation model has three characteristics, strict, informative, and status. Strict, does not allow the mixing of validation types, informative provides a warning if the schema or document type definition (DTD) cannot be found, and status provides warnings if validation cannot be performed for elements and attributes from schemas.
