On behalf of the XML Schema Working Group we are pleased to announce
the release of new Public Working Drafts for XML Schema: Structures [1]
and XML Schema: Datatypes [2].

These working drafts incorporate substantial new material, and
represent an important step forward.  The following is an extract from 
the 'Status' section of both drafts:

  The WG believes this draft to be `feature-complete': the
  functionality included here is substantially complete and is
  expected to be stable. We do not expect to add major new
  functionality, or to make major changes to the functionality
  described in this draft. Some sections of the draft (in particular
  those on conformance), and some aspects of the design (in particular
  details of the transfer syntax for schemas), on the other hand, are
  still rough and are expected to be revised.

  The WG expects to spend January, 2000, working out details,
  clarifying points of uncertainty that arise in the review of this
  draft, cleaning up inconsistencies, reviewing the design of the
  concrete transfer syntax, and making editorial improvements.

  Following that period of review and polishing, it is the WG's intent
  to issue a Last Call for Review by other W3C working groups sometime
  during February, 2000, and to submit this specification in March,
  2000, for publication as a Candidate Recommendation.  This schedule
  may vary, depending on the comments of the public and of other W3C
  working groups on this draft. Such comments are instrumental in the
  WG's deliberations, and we encourage readers to review the draft and
  send comments to www-xml-schema-comments at w3.org.

  Although the Working Group does not anticipate further substantial
  changes to the functionality described here, this is still a working
  draft, subject to change based on experience and on comment by the
  public and other W3C working groups. The present version should be
  implemented only by those interested in providing a check on its
  design or by those preparing for an implementation of the Candidate
  Recommendation. _The Schema WG will not allow early implementation to_
  _constrain its ability to make changes to this specification prior to_
  _final release_.
