DataSet can't determine 'childs'

Is it true that XML in this form is **unusable** for usage by
DataSet.ReadXml([file], XmlReadMode.Fragment) and
[DataRow][DataColumn].GetChildRows()?

Because I found that GetChildsRows() does not work. I am talking about a
DataSet which has a xsd schema.
Im suspecting currently, that GetChildRows -only- works if there is a
primarykey-foreign key relation ship.

I DO want to avoid to use the XmlDocument object to read all data! Is there
an easy fix for this?

The child(s) here is <option>

<entry>
<value>blah</value>
<entries>
<option>1</option></option>2</option>
</entries>
</entry>

I believe you will still have to define a relationship in the dataset.

I have an other dataset, which has a normal schema (without relationships)
which works. Only the schema created from the XML showed in OP does not seem
to have effect on subchilds being related to a parent element.
