How to make XML Tags Optional

Hello Guys,


Say this is my XML File

	<system_header>
		<trace_key>gsfgsrgwrw</trace_key>
		<originator>
			<domain>example</domain>
			<system_name>domain</system_name>
		</originator>
		<create_time>2000-05-24T163330Z</create_time>
	</system_header>



How can i make the Tag <trace_key>gsfgsrgwrw</trace_key> as Optional Tag and
the Value Optional

How to do it if the tag is <originator>, does the children are to be defined
optional and nullable.


Thanks
