OK - as promised, here is a more detailed write up of the various
issues as well as my proposed solution.
The root cause of this is that the W3C did not publish a schema (even
a non-normative one) for the namespace http://www.w3.org/1999/xlink.
This leaves those trying to implement XLink with the task of creating
their own schemas.
I'll give the brief summary here and then go on to describe it all in
more detail. The next stage of the problem comes from the fact that
XBRL and CIQ have created independent implementations of the
http://www.w3.org/1999/xlink namespace, both of which define things
like attribute groups and global types in that namespace which, it
could be argued, do not belong there (because the owners of the
namespace have never defined them as belonging there). These two
implementations are incompatible. In addition the CIQ implementation
has defined the traversal attributes <xsd:attribute name="to"
type="xsd:NMTOKEN">, <xsd:attribute name="from" type="xsd:NMTOKEN">
and <xsd:attribute name="label" type="xsd:NMTOKEN"> as NMTOKEN whereas
these are defined in the text of the spec at
http://www.w3.org/TR/xlink/#traversal-atts (and in the XBRL
implementation) as being NCName. To fix this all we can create a
minimal implementation of the http://www.w3.org/1999/xlink that
strictly confines itself to those things that are defined by the
owners of that namespace in the relevant spec.
OK - now for the gory detail.
Lets take a look at the XLink spec first of all:
This specification defines the namespace http://www.w3.org/1999/xlink
- see http://www.w3.org/TR/xlink/#att-method and in doing so states
"XLink's namespace provides global attributes for use on elements that
are in any arbitrary namespace. The global attributes are type, href,
role, arcrole, title, show, actuate, label, from, and to." There is
nothing in the specification that defines anything else as belonging
to this namespace.
XBRL has defined a schema as follows (a non-normative version is
available at http://www.xbrl.org/2003/xlink-2003-12-31.xsd ):
xlink-2003-12-31.xsd (normative)
