SIP sends the configured institution ID in the AO field, but nearly every SIP-using vendor I've worked with assumes that the AO field will contain the patron's home branch code instead. We've dealt with this by creating custom fields, but it would be simpler and easier if we had the option of sending the patron's home branchcode in the AO field for patron status and patron information requests. The SIP2 spec lists is simply as "The library's institution ID" leaving pretty much everything about it up to interpretation.
