There are no normative references to openmath, just examples.  However
they are real examples, to a real language.  This is the same as the
examples showing MathML embedded in HTML We use real XHTML with the real
XHTML namespace (which happens to be a W3C one) It wouldn't make sense
to replace the XHTML examples with a made up language in an example.org
namespace, and similarly it would be very confusing for the user if the
examples of how to use definitionURL to tie MathML instances to some
external semantic were barred from using real language examples.

However DefinitionURL's are in many ways like namespaces names
a MathML renderer is never obliged to resolve them. I think it is
important to show that MathML is not some strange language that lives in
isolation, but that it can be combined in various ways with other
languages both within and without the W3C. OpenMath is an important
example of such a combination and we need to be able to show such
examples. It is also important that they are just examples and not
normative...

on another point, It's rather late here so perhaps I just failed to
understand  but could you expand on your comment


Appendix K
Reference titles should be the link. The Manual of Style shows an
example reference: http://www.w3.org/2001/06/manual/#References


The cross referencing style here is as generated by the xmlspec XSL
stylesheets (The stylesheets used here are reasonably heavily
customised, but not in this area, as far as I can recall)

a typical example is this one I just cut from chapter 2, referencing XML:

   <p>MathML is an application of <a href="appendixk.html#XML">[XML]</a>,
   or Extensible  Markup Language,

That is following the house style as described at the link you gave,
isn't it?
