So can I try to outline what I take to
be an explicit version of your scheme?

1. All empty sumti places within du'u fill with zo'e.


Yes.


2. In ka abstractions, the first empty place fills with ce'u and the
  rest fill with zo'e.


Yes


  Exception (or generalization): where context indisputably demands
  a ka abstraction expressing an n-adic relation, where the value of
  n is certain, the first n empty places fill with ce'u and the rest
  with zo'e.


No.  Other {ce'u} are explicit, unmarked are {zo'e}
Unless there is an explicit {zo'e}, in which case, all {zo'e} appear and
{ce'u} are implicit.

3. EITHER (XOR):
  3a. In a ka abstraction, if an overt ce'u fills the x1 then all
      following empty places fill with ce'u.
  XOR:
  3b. In a ka abstraction, if a ce'u precedes the first empty place
      then all following empty places fill with ce'u

Wordy but OK: if {ce'u} in the first open (not filled with content sumti)
space then all blanks are {ce'u}

<A. Empty places and their sequence have to be defined as x1<x2<x3<x4<x5
   (because I can't see any other way of defining them). This means
   that {ka broda .... fa ko'a} will gardenpath people, because they'll
   misparse as {ka ce'u broda}. There's probably no way round this;you
   have to wait to the end of tbe clause to know where the ce'u and
   zo'e go. Your only safe bet to avoid gardenpathing is to use overt
   ce'u within du'u>
No, defined by space: first available space, etc.  If first occurrent
_expression_ is {fe S} then there is assumed to be a space unfilled before it
and so on.  We can (and will if need be) establish fixed order to prevent
gardenpathing of that sort.

<B. Rules 2-3 raise further problems of specification:

   i.  Does an empty place within a nonempty x1 precede an empty x2?

   ii. If nonempty x3 precedes nonempty x2, does an empty place within
       x3 precede an empty place within x2?>
Now that is interesting.  I (nor anyone else that I can find) didn't think of
the gaps in a {ka} phrase being within subordinate pharses.   I can see that
that will generate some problems for interpretation in some cases (if the
internal phrase is intensional, for example) but the question of how toapply
the conventions -- other than the fact that it opens the possibility for many
more that 5 omitted placeholders) can be handled rather easily, whichever
ways sems to work best.  I tend to favor linear orders, so I wouldgo with
"yes" to both your questions (except for being unsure what "x3 precedesx2"
means)

<C. {ka ce'u ce'u ce'u ce'u ce'u klama} = {la'e zo klama}, so it may
   be that Rule 3 doesn't have to be relied on that much.>
While I think that what C intends is correct, the grammar is not quite right,
for the {ka} phrases is a selbri and the {la'e} is a sumti.  So, they do play
different roles sometimes.  I think doing lambda reduction with {la'e zo
klama} would be a serious mistake generally.  But the equation does reduce
the need for {ka ce'u klama} say.

<D. Nor does Rule 2 have to be relied on that much, because {ka ce'uzo'e
   zo'e zo'e zo'e klama} = {lo'e klama}. >
I gather (I have not been following that part of this muddle closely--
keeping tack of the {ce'u} has been quite enough for now) that you and xod
have come to this conclusion.  I can't think where it comes from (but I will
look) nor can I imagine why it would be true on the basis of anyhting in the
Book or the history of Lojban (making allowance for the misgrammar again,
even).  A typical broda is a broda, not a property (though, admittedly, not
necessarily an existing broda either).

<     ko'a ce ko'e simxu loi ka (ce'u) (ce'u) prami

   could be rendered by something like

     ko'a ce ko'e simxu lo'e prami be (tu'a) ce'u>

While I agree that a {ka} may make more sense than a {nu} in simxu-2 (the
consequences need looking at) I can't make much sense out of either of these
sentences.  What would a mass of properties be, since there is only one
property here, le ka ce'u prami. Nor is it clear what that has to do with a
typical lover of  whatever that all evaluates to (not much at a glance).
I have enough trouble with Lojban, without trying to deal with Andban and
other Nalgols (I almost miss guaspe!)

<Either:

  I. Revert to my du'u/ka/si'o proposal>
Aside from being metaphysicaly and grammatically suspect, it is markedly less
efficient than this one in test cases and wastes a good (maybe someday
useful) cmavo.
<or:

  II. a. Leave ka grungey, i.e. totally reliant on glorking.
      b. To avoid relying on glorking, use du'u, lo'e and la'e zo.>
Nah.  The one is imprecise, the other is unintelligible in the context of
Lojban and as taken to deal with {ka} issues.
