Yes, I see that for instance a MathML example points to a definitionURL
for N. MathML is however a W3C spec and if MathML needs OpenMath
definitions OpenMath could be quoted and cited as a normative
reference. I should point out that W3C has a persistence policy [1].
Non-resolving openmath.example.org URIs are my suggestion based on a
single occasion of a domain change causing harm that no one could have
predicted which is now part of an un-modifiable W3C resource. W3C
Publication Rules [2] allow any validating example at this time so of
course MathML is free to use openmath.org.

Hope that explains. :-)
