I've found that the following works for my needs (which was just to
produce lists of categorical and non-categorical variables to document
output for other people) by using the variable labels produced by xi:
local xid
local not_xid
foreach v in `vars' {
local label: var label `v'
if strpos("`label'","==")>0 {
local lbl = substr("`label'",1,strpos("`label'","==")-1)
label var `v' "`lbl'"
local xid `xid' `v'
}
else {
local not_xid `not_xid' `v'
}
}
local label2
local xid2
foreach x in `xid' {
local label2 `label2' `:var label `x''
}
local xid2: list uniq label2
I am aware that it wouldn't work to produce actual variable names for
long names that had been abbreviated or for "non-standard" xi
settings, but it solves my specific problem for the dataset I am
working on.

Sorry, I am left more confused than before.
Either way, I can't see an easy way of working back from
what is left in memory after -xi:- to what was fed to it.
This includes looking at -s()- results.
