Dmitry,

Possibly the problem is that the boolean element is not really empty, because it's still being specified, even when there's nothing in the element tag.

IOW, you have in your XML an "empty" tag that looks like this:

<req_entry></req_entry>

or maybe like this:

<req_entry />

The point is that the XML shouldn't contain the tag at all. Since you have a schema defined, the DataSet should then put the default in for the missing tag. Where did your XML file come from?

I thought that specifying the default value (false) in the schema file will set the value as false. But it does not. Here is the code of how I am loading the XML:
