Usage of PURL in the ISO/IEC 29500

These days, IRIs are often used as names of abstract things.  Our use
of PURLs for
identifying an application description is an example.

Some people use IRIs as names and do not bother to provides resources.
Others would like to provide some resources.  RDDL was invented by those
who would like to provide resources for namespace names.

In our case, we have no resources.  Personally, I see nothing wrong.  But
I know that some others might want to provide resources such as HTML
documents explaining application descriptions.

I have no ideas.  Prose in HTML documents?

As far as I know, there are no such DRs.

OOXML is not the first attempt for describing "application descriptions".  But
I am aware of no successful attempts.
