Using the DOMConfiguration users can change behavior of the DOMParser, DOMSerializer and Document.normalizeDocument(). If a DOM implementation supports XML Schemas and DTD validation, the table below defines behavior of such implementation following various parameter settings on the DOMConfiguration. Errors are effectively reported only if a DOMErrorHandler object is attached to the "error-handler" parameter.

Layout table: the first cell contains the value of schema-type parameter, the second contains the value of validate parameter, the third contains the value of the validate-if-schema parameter, the 4th contains the actual document schemas, the 5th contains the output of such configuration, the 6th list addition parameters that can be effected.1 "schema-type" "validate" "validate-if-schema" Instance schemas, i.e. the current schema Outcome Other parameters

21`null`	11`true`	11`false`	21DTD and XML Schema	21Implementation dependent	21 The outcome of setting the "datatype-normalization", "element-content-whitespace" or "namespaces" parameters to `true` or `false` is implementation dependent.

21`null`	11`true`	11`false`	21XML Schema	21 Validate against XML Schema	21 The outcome of setting the "namespaces" to `false` is implementation dependent (likely to be an error). Setting the "element-content-whitespace" to `false` does not have any effect on the DOM.

21`"http://www.w3.org/2001/XMLSchema"`	11`true`	11`false`	21DTD or XML Schema or both	11 If XML Schema is found, validate against the schema. Otherwise, report an error.	21 Setting the "datatype-normalization" to `true` exposes XML Schema normalized values in the DOM. The outcome of setting the "namespaces" to `false` is implementation dependent (likely to be an error).
11`false`	11`true`	11 If XML Schema is found, validate against the schema.
11 `"http://www.w3.org/2001/XMLSchema"` or `"http://www.w3.org/TR/REC-xml"`	11`false`	11`false`	11DTD or XML Schema or both	11 If XML Schema is found, it is ignored. DOM implementations may use information available in the DTD to perform entity resolution.	11 Setting the "datatype-normalization" to `true` of `false` has no effect on the DOM.

NOTE:
If an error has to be reported, as specified in the "Outcome" column above, the DOMError.type is "no-schema-available".
