<table> element with <table> element ... loading dataset

[timnels]

I've got a bizzare issue where I have an XML file to load into a data
set like:

<conversion>
<table name="parent">
<table name="child">
</table>
</table>
<table name="another parent">
....
....
</conversion>

I've got an XSD that describes the table element, but how would I
describe the child table. Can I put a table element in a table
element? Is this even supported/possible in .Net. How will the
resulting dataset look? Right now it just treats the child <table>
element as another table, and when it saves back to XML, it destroys
the relationship.
Your thoughts?
