The next revision of the draft EchoAPI RFC is now available:
http://bitworking.org/rfc/draft-gregorio-02.html
and if your are curious, the original XML is also available:
http://bitworking.org/rfc/draft-gregorio-02.xml
Changes from the last version:
- Entries are no longer returned from POSTs, instead they are retrieved via GET.
- Cleaned up figure titles, as they are rendered poorly in HTML.
- All content-types have been changed to application/not-echo+xml.
