The answer lies in the use of compound double quotes.
Try something like
xla(1 `" "first" "group" "' 2 `" "second" "group" "')
If you think of
`"
i.e. <left single quote><double quote>
as a left delimiter
and
"'
i.e. <double quote><right single quote>
as the corresponding right delimiter, then
you won't go wrong, given the school algebra-like
rule that delimiters must be matched in pairs.
I don't know where this is documented either;
I too would be grateful for a manual or
on-line help pointer, for this reason: if it
isn't documented in at least one of those
sources, it would be a good candidate for
a Stata Journal Tip.
