(attName string)

// name. It returns nil if the child attribute with the given name does not
// exist or if the child attribute does not have a default value.
func (a *AttributeExpr) GetDefault(attName string) any {
	if o := AsObject(a.Type); o != nil {
		att := o.Attribute(attName)
		if att.DefaultValue != nil {
			return att.DefaultValue
		}
		if ut, ok := att.Type.(UserType); ok && !IsObject(ut) {
			return ut.Attribute().DefaultValue

// SetDefault sets the default for the attribute. It also converts HashVal
// and ArrayVal to map and slice respectively.
