generate-id() will give a unique id for the context node. If that is the 
same both times your template is processed then you will get the same id.
So generate-id() is useful if you have e.g.

<list>
   <foo>...</foo>
   <foo>...</foo>
   <foo>...</foo>
</list>

in your input and then write a template for 'foo' elements in the stylesheet
   <xsl:template match="foo">
     <li id="{generate-id()}">
       <xsl:apply-templates/>
     </li>
   </xsl:template>
