Need help with XML empty column

[DerCardano]

This is part of my xml

<Lost>
<Lost_by>buyer</Lost_by>
<Lost_agreement />
<agreement_description>GO FIND IT!</agreement_description>
</Lost>

I can map everything just fine except <Lost_agreement />
After i export mapped XML, <Lost_agreement /> is missing. it becomes

<Lost>
<Lost_by>buyer</Lost_by>
<agreement_description>GO FIND IT!</agreement_description>
</Lost>

But <Lost_agreement /> part is crucial and must be. How can i achieve it?
