Namespaces	Gets or sets the XmlSerializerNamespaces to use with this schema object. (Inherited from XmlSchemaObject)
Parent	Gets or sets the parent of this XmlSchemaObject. (Inherited from XmlSchemaObject)
Particle	Gets or sets one of the XmlSchemaGroupRef, XmlSchemaChoice, XmlSchemaAll, or XmlSchemaSequence classes.
SourceUri	Gets or sets the source location for the file that loaded the schema. (Inherited from XmlSchemaObject)
UnhandledAttributes	Gets or sets the qualified attributes that do not belong to the current schema's target namespace. (Inherited from XmlSchemaAnnotated)

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
