XLink 1.1, let's get the party started

See

  http://www.w3.org/XML/Group/2004/xmlcore/xlink11/

and

  http://www.w3.org/XML/Group/2004/xmlcore/xlink11/diff.html

In particular:

New section 1.2:

  1.2 Origin and Goals for XLink Version 1.1

  XLink Version 1.1 is intended to be a second edition of XLink 1.0 in
  all but name. It makes one normative change to XLink 1.0, providing a
  default value for the type attribute in the XLink namespace, and two
  informative changes, adding W3C XML Schema and RELAX NG Grammars for
  XLink.

  In XLink 1.1, the semantics of an element with an href attribute in
  the XLink namespace that does not also have a type attribute in the
  XLink namespace is that the element is treated as if it had a type
  attribute with the value \u201csimple\u201d. In other words, if href
  is present and type is absent, the element is an XLink simple link.

Revised section 3.2:

  3.2 Markup Conformance

  An XML element conforms to XLink if:

     1. it has a type attribute from the XLink namespace whose value is
        one of "simple", "extended", "locator", "arc", "resource",
        "title", or "none", and

     2. it adheres to the conformance constraints imposed by the chosen
        XLink element type, as prescribed in this specification.

  Or

     1. it has an href attribute from the XLink namespace and does not
        have an type attribute from the XLink namespace, and

    2. it adheres to the conformance constraints imposed by the XLink
        "simple" element type, as prescribed in this
        specification.

  This specification imposes no particular constraints on schemas;
  conformance applies only to elements and attributes.

Two new (non-normative) appendixes for W3C XML Schema and RELAX NG
Grammars and minor editorial twiddles here and there.

                                        Be seeing you,
                                          norm
