FIM Group XPATH filter limitations

Hi,

We have reviewed the XPATH filter limitations as per: http://technet.microsoft.com/en-us/library/ff356871%28WS.10%29.aspx

However, are there any limitations / best practices as to the number of XPATH filters per Set / Group?

For example, we may have a FIM Group that may be made up of 24 different 'OR' XPATH filters - would this be a performance hit on FIM? Is there a limit on these?

Thanks,

SK
