Looking through the latest Keystone code and developer guide I have noticed some differences in the usage of PUT and POST CRUD operations. 

Resource Creation      admin.py           Developer Guide Says   
................................................................
Tenant                 PUT or POST        PUT in table 5.2.4 OR POST in section 5.4.1 ?
Tenant Group           PUT or POST        NA
Users                  PUT or POST        PUT in table 5.2.2 
Global Group           PUT or POST        NA
Role Ref               POST               POST in table 5.2.6 and section 5.6.4
Endpoints              POST               POST in table 5.2.5 and section 5.5.4


Questions:
Is there any reason why Tenants and Users allow PUT and POST for creation while Roles and Endpoints only allow POST?

Would it be possible to go only with POSTs in the above areas?

The developer guide does not match the current code in the above areas, these may just be typos at this stage but it would be good to clarify what the real APIs should be.
