Please read the documentation[^]. Even if document is nullable it must be "visible".
To be able to "remove" xml element, you have to create xsd file, in which you have to declare this element that way:

XML

<xs:element name="sun" type="xs:string" minoccurs="0" maxoccurs="unbounded" xmlns:xs="#unknown" />

It means that sun element is optional (not required).

See: Controlling XML Serialization Using Attributes[^]
Attributes That Control XML Serialization[^]
<xsd:attribute xmlns:xsd="#unknown"><xsd:attribute> Element[^]

Use System.ComponentModel.DefaultValueAttribute
like

C#

[DefaultValue(0)] public int sun { get; set; }

or if 'Sun' is a class or customtype add something like this to your serialized class

C#

public bool ShouldSerializeSun() {
   return sun != null;
}
