BTW, it occurs to me that in fact the major advantage of doing a higher
level extension element is actually to change the hint extension model from
explicit XML to what you might call the "generic property" approach that a
lot of people favor.
In other words, this:
<Extensions>
<krb:Hint>...</krb:Hint>
<ip:Hint>...</ip:Hint>
</Extensions>
becomes this:
<Extensions>
<disco:Hint Type="...KRB">...</disco:Hint>
<disco:Hint Type="...IP">...</disco:Hint>
</Extensions>
People not especially enamored of XML seem to favor the latter as a
"simpler" extension model, though personally I'm not a big believer that it
makes much difference.
But I suspect that's the real decision point (and maybe that's what you
meant).
