[SI-LIST] : IBIS models

I have found several IBIS models that use the [Pin] keyword but only
model a couple of pins. For example, an octal buffer in a 20-pin
package that only includes statements for one buffer input pin, one
buffer output pin, Vcc and Gnd. My reading of the IBIS spec would say
that this is non-compliant. In Section 5 under "Usage Rules" for the
[Pin] keyword the first sentence states "All pins on a component must
be specified.".

1) Am I correctly interpreting the IBIS specification?

2) How common are models of this type?
