Optional Readonly__invariantPrevents rule from losing nullable type information.
ReadonlylocalMatches the QName.localPart of the element. If undefined, this will match against
the property name from XmlRules.
ReadonlynamespaceMatches the namespaceUri of the element or attribute.
If null, this will only match against a null namespace. If undefined, this will default to the namespace of the parent element for elements, or null for attributes.
Note that attributes do not inherit default namespaces as elements do.
ReadonlyrequiredIf true, a parsing error will be thrown if the value is undefined.
ReadonlyrulesReturns the schema for the matched element.
