Adding element in middle of xml using xslt

Below is the actual xml:

<?xml version="1.0" encoding="utf-8"?>
<employee>
 <Name>ABC</Name>
 <Dept>CS</Dept>
 <Designation>sse</Designation>
</employee>

And i want the output as below:

<?xml version="1.0" encoding="utf-8"?>
<employee>
 <Name>ABC</Name>
  <Age>34</Age>
 <Dept>CS</Dept>
  <Domain>Insurance</Domain>
 <Designation>sse</Designation>
</employee>

Is this possible to add XML element in between using xslt? Please give me sample!
