Hi NG!
I have a question to the following XML structure (or similar to this):

<History>
<Technique name="AB1" date="02/22/07 08:18">
<Voltage>230</Voltage>
<Size>
<X>12</X>
<Y>12</Y>
</Size>
</Technique>
<Technique name="BB1" date="02/22/07 08:25">
....
</Technique>
</History>

The History can have one or more Technique entries.
A technique is defined by the name and the date.
A technique contains different parameters.

According the MSDN I have 2 possibilities to create a XSD which allows
me to save my data.
1.) a nested XML structure (as displayed above)
2.) Use of Key/Keyref.

I just have to check if the values has been changed and if so create a
new technique entry.
Which is the best way to implement my needs ? What do you recommend
and why ?

Thanks

schaf,
This really does not relate to the C# language. Try the ADO.NET newsgroup.
