> appear identical to the user but which are treated as distinct by XML
> processors.

> A document can still be well-formed, even if it is not in a normalized

Francois has said that he does plan to process this erratum.

and work with Henry to determine exactly what/where are the latest
DTDs and schemas.

> David Carlisle has a comment on this discussion.

David requests that we do not default xlink:type in the DTD
(and other schemas).

Norm sent email agreeing with David.

Consensus not to default xlink:type and not to require href.

ACTION to Henry and John:  Update the DTDs and Schemas (both for full
and simple conformance) so that the xlink:type attribute has no
default (e.g., is #IMPLIED).

> Henry finds the DTD/RelaxNG/XSD fragments throughout the spec unhelpful
> and would like to remove them (leaving them only in the appendices).
> 
> There was also discussion about just what simple conformance is:
> does it require href or not? For example, if something has
> xlink:type="simple" but no href, it is still a simple link.
> See also
> http://www.w3.org/TR/2008/WD-xlink11-20080331/#app-reqs-simple
> But then the definition of simple link at
> http://www.w3.org/TR/2008/WD-xlink11-20080331/#simple-links
> says it associates exactly two resources, and how can it do that
> without an href attribute?  But 4.1 does say that href is optional
> in a simple link.
> 
> We had Norm-less consensus to define simple conformance to
> require href.

But during today's telcon, we changed our mind and decided that
simple conformance does not require href.  Norm has specific 
wording in mind.

ACTION to Norm:  Modify the XLink 1.1 spec to reflect our latest
wording on simple conformance.

> 
> ACTION to Henry: Modify the simple conformance XSD to make href
> required.
> 
> ACTION to John: Modify the simple conformance RelaxNG to make href
> required.
> 
> ACTION to Norm: Update the prose in the spec to redefine simple
> conformance to require href.  For example:
> "...with respect to simple links.  In other words, elements..." ->
> "...with respect to simple links with an explicit xlink:href
> assignment.
>  In other words, all and only elements..."

All 3 of the above ACTIONs are now RESCINDED.

And it reflects input from several WG members now.

During the telcon, we went through the issues list looking at
general preferences.

ACTION to Henry:  Propose a solution to issue 15 (the productions)
in email, possibly using a xref to the XML spec itself.

ACTION to Paul:  Continue to suggest discussion/resolutions
of issues in email.

> ACTION to WG members:  Send to the list email with your preferences
