Describe differences in functionality between normal EPP and REPP

[mwullink]

A command MUST only contain a single object to operate on, for example

• with repp, check command will only support 1 domain per request
• check used HEAD, no req/resp message-body content
• no login/logout command
• no sessions
• newPW from login is now /password resource
• version from login is now part of URL
• lang from login is now http language request header
• client need to add schemas used to each request using new header
