Comment:

This "all resources specified by" statement is a very informal way to "enumerate" the IRIs from the iriset. I guess the
reason is that the iriset can be specified by a regular expression, and so a finite enumeration is not always possible,
right? I suggest to say a few words about this, because I assume that this sort of notation will confuse people.

WG Notes: Please note the phrase "the IRI set has been elided for clarity (the semantics of the IRI set is discussed in Section 4 below)" immediately above Ex 3-1. We simply defer showing both POWDER/XML irisets and their RDF translations for clarity, as these have not yet been introduced, and informally describe what should be there. Please let us know if your editorial comment persist after this explanation and you think that this should be made more explicit in Ex 3-2, 3-3, and 4-3.
