I believe the current prescription is that scope follows left-to-right, except for {na} (or NA?), which has maximally wide scope over the bridi.
This exception is a pointless complication that leads to confusion. It should be done away with. (The only defence of it has come from Nora (on jboske & phpbb), hingeing on the interpretation of nago'i. This is addressed on phpbb & will be recapped on the wiki in due course when we get round to writing up something on the interpretation of bridi anaphora.)
The scope rules, then, are as follows:
-----
xorxes:
We also need to consider the scope of quantifiers in tagged terms with respect to the scope of the tag. There seem to be two options:
And: Are you talking about {PA1 ROI PA2 broda}?
xorxes: Yes, but it applies to other tags as well. Does {di'i ze broda} mean that the event occurs regularly within each of the seven broda, or that the seven broda are regularly distributed? I think the latter has to be {di'i lo ze broda}, and that {di'i ze broda} gives the former, i.e. {di'i} is within the scope of {ze}, just like the selbri of the bridi this term belongs to.
