Please forgive the noob question (especially if this isn't the correct place to ask this...)

The fb tag "if-is-user" allows the ability to check for multiple user IDs by separating the user IDs with a comma. Does the "is-in-network" tag support the ability to check if a user is a member of at least one group by using the same method?

For example, if I wanted to determine if someone was part of either Oklahoma State (network ID 16777388) or University of Oklahoma (network ID 16777313), could I use the following?:

<fb:is-in-network network="16777388,16777313">

 (code to show bedlam football pictures)

</fb:is-in-network>

If the "is-in-network" does support this capability, shouldn't it be added in the tag documentation similar to what is shown for the "if-is-user" tag?

Thanks,

Bill
