RE: CR20: proposal 4a (crisper version)

AIUI the rationale for removing a default value for wsa:To is that in
more than half the cases (requests, especially over HTTP), the anonymous
value doesn't have much utility, as it's generally undefined or banned.

 

But in practice, no single default value has much utility as a default
in request messages.  But the default value of anon in HTTP responses
(and probably other protocol's responses) does clearly have utility.

 

To disallow a default in the request case seems entirely reasonable, but
throws out the baby with the bathwater by removing the default
generally, in particular from the case where it actually has utility.
On the other hand, the harm caused by having a default that can't be
used in some cases isn't any worse than the cure (not have a default at
all).

 

So, -1 to losing the default value of wsa:To.

FWIW, that's choice 2 in "Choices for CR 20" [1]
