You can find the latest released draft on the Specification page. Older drafts are expired, but may be of historical interest.
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.
IETF draft documents do not correspond directly with meta-schema draft numbers, as a new IETF draft may be published to fix bugs in a previous document without changing implementation requirements or moving to a new meta-schema. This is because it is not possible to edit drafts once they are published, it is only possible to replace them with a new corrected draft.
