David,
For your idea is allow all SAP for SNA, but the question that Wlias ask for
SAP 04 and 08 I think it should be
access-list 200 permit 0x0404 0x0d0d
access-list 200 permit 0x0808 0x0d0d
and after that you can apply to remote dlsw statement or interface depand on
what thw question ask to do.
am I right ?

Elias,
You can use the following to permit all SNA types and deny everything else:
access-list 200 permit 0x0000 0x0D0D
access-list 200 deny 0x0000 0xFFFF
Here is a link:
