How are you going to do this?

fn:current-dateTime() will return the same value each time.

No, I was implying adding a unique number, not necessarily a timestamp. One way (and imho the preferred way) is doing this by retrieving the id of a newly created node:

<xsl:function name="f:my-id">
   <xsl:variable name="new-node">
         <node />
    <xsl:sequence select="generate-id($new-node)" />

Now, calling f:my-id() will always return a unique id within the session. If you also need a unique id globally, add a timestamp or use my GUID techniques.
