Documentation problem

I was just reading about the observe method implemented in .Net client library, found two things problematic:

1. Here in the wiki page : http://www.couchbase.com/wiki/display/couchbase/Observe
there is a statement that says : "In the examples above, the ReplicateTo and PersistTo are enums with values from 1 to 4." which is incorrect as we know that replication is only allowed till 3 nodes and the enum ReplicateTo has values = 0,1,2,3. For PersistTo, the values are from 0 to 4.

2. No information about Observe is found in sdk documentation (may be i couldn't locate it) : http://www.couchbase.com/docs/couchbase-sdk-net-1.2/
