Public Enum ConformanceLevel
The XmlReader or XmlWriter object automatically detects whether document-level or fragment-level checking should be performed, and does the appropriate checking. If you're wrapping another XmlReader or XmlWriter object, the outer object doesn't do any additional conformance checking. Conformance checking is left up to the underlying object.
The XML data complies with the rules for a well-formed XML 1.0 document, as defined by the W3C. This level of checking ensures that the stream being read or written can be consumed by any processor as an XML 1.0 document.
The XML data is a well-formed XML fragment, as defined by the W3C. This conformance level represents an XML document that might not have a root element but is otherwise well-formed. This level of checking ensures that the stream being read or written can be consumed by any processor as an XML 1.0 external parsed entity].
When you create an XML reader or writer instance, you can use the XmlReaderSettings or XmlWriterSettings class to specify the features that you want the new instance to support. One of the features that you can configure is the level of conformance you want to enforce on the XML data.
Creating a compliant reader or writer guarantees that the XML data being processed complies with the specified conformance level. If the stream being read or written doesn't comply with the conformance level, an exception is thrown.
Document-level checks with the
ConformanceLevel.Document enumeration member enforce fragment-level checks (the
ConformanceLevel.Fragment member) and also ensure the following:
The top-level item doesn't have any nodes other than the XML declaration, DTD, element, comment, white space, or processing instruction.
The XML data has one and only one top-level element node.
