Appendix B.  RELAX NG Compact Schema

   This appendix is informative.

   The Relax NG schema explicitly excludes elements in the Atom
   namespace that are not defined in this revision of the specification.
   Requirements for Atom Processors encountering such markup are given
   in Sections 6.2 and 6.3.
