You are correct.  The "Annotea Protocols" document is not a proper 
specification.  If you look through the recent postings on this list, 
you will see a number of messages from me that point out "holes" in the 
document; i.e. points where the document does not adequately describe 
the required behaviour of an Annotea server (and client).  Those 
messages are based on what I learned in implementing "Danno".

What Urs said is also true.  The document is "out of date" in the sense 
that we want to use Annotea to do far more than the "Annotea Protocols" 
document envisages.  Support for the bookmarks schemas, SPARQL queries 
and so on are some of the examples.

There are none.

Again, there are none.  Actually, it is worse than that.  The "annotest" 
server is known to NOT correctly implement the protocols as described in 
the Annotea Protocols document.  IIRC, annotest requires an incorrect 
query name to fetch replies to an annotation, and it uses the DC 1.0 
namespace rather than DC1.1 which is used in the examples in the Annotea 
Protocols document.  (And there may be other issues too.)

The best I can suggest is to read the Annotea Pro carefully, read my 
messages (and others) on this list, and try to figure out something that 
works for your particular use-case.  Also, if you care about 
interoperability with other people's clients and/or servers, test your 
clients against their servers and vice-versa.  I'd pay most attention to 
client/server implementations that people are actively working on.  For 
example Annozilla and Danno/Dannotate.  Finally, you can always ask 
questions on this mailing list :-)
