Well, yes - as far as I can tell, Song and Bender 2012 does
underspecify in a way that allows a very fine-grained control with
ICONS in a way which makes sense formaly. I've just (re)skimmed the
paper and haven't looked at the associated grammar, but I raised the
question I did because I'm not sure whether the ERG analysis is
intended to be the same or not. There is a difference between
having an ICONS element with an underspecified info-str relation and
not having an ICONS element at all. We might be able to get the
fine-grained control using the ERG analysis but possibly only with a
different interpretation of ICONS.<br>

<div>my ideal would be a set-up where the provider of generator
inputs has three options: (a) request topicalization (or
similar), (b) disallow it, or (c) underspecify and get both

<div>we used to have that level of control (and flexibility) in
the LOGON days where there were still messages: in the message
EPs, there were two optional ‘pseudo’ roles (TPC and PSV) <span></span>to
control topicalization or passivization of a specific instance
variable. effectively, when present, these established a
binary relation between the clause and one of its
nominal constituents. if i recall correctly, blocking
topicalization was accomplished by putting an otherwise
unbound ‘anti’-variable into the TPC or PSV roles.</div>

I believe this was designed to imitate the long-standing
condition that the MRS of generation results must be
subsumed by the input MRS. The observed behavior seems to
me to be the correct interpretation of the subsumption
relation with ICONS involved. Note that an MRS with an
extra intersective modifier would also be subsumed, for
example, but such MRS are never actually generated since
those modifier lexical entries never make it into the chart.<br>
<br>
It’s certainly reasonable to ask whether (this notion of)
subsumption is really the right test. I’ve met lots of
folks who prefer to turn that subsumption test off
entirely. I guess it’s also possible that the subsumption
test is right for the RELS portion of the MRS but not for
the ICONS, though that seems a bit odd to consider.
However, given that we don’t have many ideas about
truth-conditional implications of ICONS, maybe not so odd.<br>
<br>
I don’t really have much to offer in terms of opinions about
what the right behavior should be. I (believe I) just
implemented what others asked for a couple years ago :-)<br>

I have a question about generation. If I implemented the
behaviour described in <a moz-do-not-send="true"
href="http://moin.delph-in.net/IconsSpecs" target="_blank">http://moin.delph-in.net/IconsSpecs</a>
there doesn't seem to be a way of specifying that I want a
`normal' ordering for English.<br>

With an exact ICONS check, I can select realizations with
the same ICONS (modulo order of ICONS elements, of course,
in the case where there's more than one element). But with
the <a moz-do-not-send="true"
href="http://moin.delph-in.net/IconsSpecs" target="_blank">http://moin.delph-in.net/IconsSpecs</a>
behaviour, there's no way of specifying I want a `normal'
order - if I don't give an ICONS, I will always get the 5
realisations. In fact, as I understand it, I can always end
up with more icons in the realisation than in the input, as
long as I can match the ones in the input.<br>
