Hello, I have an XML document that contains:

<data>
<datum value="123"/>
<datum value="234"/>
<datum value="99"/>
<!-- Some more data... -->
</data>

I wish to use a XSLT document to output:

<data>
<min value="99" />
<max value="234" />
<avg value="..." />
</data>

This does not seem too complicated, but I cannot figure how to do it.

I do not mind if I have to rewrite my question in terms of:

<datum>123</datum>

and my answer as:

<min>99</min>

Thank you very much in advance.
