1.  Introduction

   While developing various tools and software related to RDAP, issues
   have been found and are documented below.  This document should help
   in writing future version of the specifications and provide better
   conformant deployment.  It is split in various sections based on
   where the fix should be applied.  Obviously, there are different
   levels of severity of the issues, including nits or very minor.  The
   actual instances and organisations running the RDAP servers where the
   issues were found are not listed.
