I think I didn't make myself clear. Regarding the baselined CLL 'grammar', which is a pseudosyntax, you can either (a) reject it as irrelevant junk (-- the move I would favour) or (b) treat it as an actual syntax. If you go for (b) then the members of a syntactic category must have the same behaviour with respect to the rules that translate into logical form, and hence if {tu'a} is in LAhE syntactically then (by definition) it is in LAhE semantically.

While I agree that the baselined formal grammar is not quite a syntax in your sense, it is also not merely a pseudosyntax (just combinatorics of morphophonological forms). There is a high correlation between the morphophonological combinatorics and the logical form, even if it's not (yet?) quite perfect. For most selmaho, all of its members do have the same behaviour with regard to logical form, but it's true that some important selmaho do have many oddball members (the most egregious probably being UI or PA).
 
It is a pseudosyntax, but there also exists an implicit undocumented syntax and an unlinguistic mapping from the pseudosyntax to the implicit syntax, which makes the pseudosyntax look like more than junk. Once the actual syntax is documented, the pseudosyntax could safely be discarded.
 
The key requirement for the syntax is that it constitute (the syntactic aspect of) logical forms. Additionally, tho, for a language whose creators and users are so keen for it to be used and spoken as a human language, it is likely that the syntax should look like the syntax of a human language. It's probably to soon (in the development of linguistics) to say what that is, but traits like headedness, lexicality of heads (and/or constraints on nonlexicality of heads), and (plausibly but more controversially) binary-branching look like plausible candidate universal features. A syntax whose phrases are all binary-branching and lexically-headed looks a good bet to not fall outside human language.
 

Actually, (a) and (b) presuppose that we are describing a language, but there's also option (c), which is to describe something that isn't actually a language but nevertheless involves a set of rules mapping pseudosyntax to logical form. I guess (c) is what you're actually doing, which as an intellectual exercise is fair enough.

There may also be a middle road between rejecting the formal grammar as irrelevant junk and treating it as a masterpiece that can't be touched: treat it as a first draft that needs to be modified here and there to become closer to a real syntax. In the particular case of "tu'a" in LAhE, for example, we can just create two subselmaho LAhE1 and LAhE2 which share the same morphophonological combinatorics but differ (slightly) in the logical form behind them. 
 
It can't be a first draft, because it can't be a syntax, but it can be a stage in the development of a first draft.  The discussions you and Martin are having can lead to a notion of what the syntax is like. You can then work out rules that generate that syntax directly, instead of deriving it by rule from the pseudosyntax. So what Martin is doing is maybe the most important work that's been done for Lojban, tho it's all going over my (busy elsewhere, insufficiently-attentive, and somewhat foggy) head.
