Ok, I looked at it.  His representation allows for restricting occurances
of avps to one and many.  

Incorporating his changes yeilds:

<!ATTLIST avprule
        name IDREF #REQUIRED
        position (first | last | unspecified)  "unspecified"
        maximum CDATA "none"
        minimum CDATA "0"
>

Allowing for both position constraints, an avp being required (minimum=1), and
allowing for at most one avp (maximum=1)
