pattern/@documents: definition of behaviour

[AndrewSales]

In ISO 2020, 5.4.10, para 2, it says re the value of @documents:

"If the expression evaluates to more than one IRI, then the pattern is sought in each of the
documents. "

I think this should be re-worded: the part before the comma implies that the second half only happens if there is more than IRI and can leave the reader wondering what happens if there is only one.

Something like this instead: "The pattern is sought in each of the documents located at the resulting IRI(s)."

This would also then lead naturally into describing error handling, per #47.
