 **A note on draft naming and numbering:**  
 IETF Internet-Drafts (I-Ds) are named with the editor's name and a sequential number which resets with each new editor.  Meta-schemas are numbered sequentially.  Additionally, drafts 00-03 used one document for all three current specs.  Most people find it easier to remember the sequential meta-schema numbers, so those are used throughout the site.
