I was looking at your proposal from the perspective of other fault
subcodes, in particular wsa:InvalidAddress.

wsa:InvalidAddress reads:

  Specifies that an [address] was invalid, [Details] MAY contain a
  wsa:ProblemIRI element in addition to the <wsa:ProblemHeader>
  element or <wsa:ProblemHeaderQName> element.

I was curious about why we suggest to use wsa:ProblemIRI for problems
with [address] in wsa:InvalidAddress, when you don't for [action] in
wsa:ActionMismatch. I believe that the answer is that
wsa:ProblemHeader can already be used to carry the information that
wsa:ProblemIRI would contain.

So wsa:InvalidAddress seems to have a similar redundancy issue, that
we could solve by removing wsa:ProblemIRI as a suggested content for
[Details].

BTW, I was wondering about the subtle difference between
wsa:InvalidAddress and wsa:DestinationUnreachable. Are we expecting to
use the former when the content of [address] is not an IRI as
expected? If so, this is another argument against wsa:ProblemIRI here
as the type of this element is anyURI.

Cheers,

Hugo
