Thanks for reviewing it. 

> - Section 5.1.4 should be titled "EPP <transfer> Query Command" because 5.1 is about "EPP Query Commands". The normal transfer command falls under "EPP Transform Commands”.

Noted, will update in next version. 

> - In Section 7, the statement "For a label size of 64 characters, the list of label variants may reach up to 320 entries." The 320 is not mathematically right. To be exact, it should be 5 power of 64. :)

Right… Must have written this on a pre-coffee morning. It’s 5 possible code variants over 64 positions, so 5x5x5x5x… 64 times, so 5^^64, or 5.4E44. More than enough to create a DOS on the server from a single registrar query, even if the registrar is unwillingly participating (might be an unchecked request from the public registrant side, the web interface for example). Will update that text.
