Restarting the numbering sequence of a fo:list-block

For the life of me I cannot figure out how to restart
the numbering sequence of a fo:list-block without using the
"from" attribute of xsl:number element. I don't want to use the
"from" attribute because it seems to be selection criteria
oriented which for me doesn't really pertain. I've searched the
FAQs, 3 different books, tutorials, through the W3C specs, all
to no avail.

 My First List:
 1. entry 1
 2. entry 2

 My Second List:
 1. entry 1
 2. entry 2

 My First List:
 1. entry 1
 2. entry 2

 My Second List:
 3. entry 1
 4. entry 2

Thanks
