Client developers occasionally ask for being able to combine <before/>
and <after/> in MAM requests, as this would help with filling gaps in
the local history. But I agree this is quite obviously not supported by
XEP-0059. You page through the result set by turning either to the next
or to the previous page, you can't do both at once. Supporting a
different model would require more changes to the XEP, I think.
> In any case, I'd like to see the XEP updated to be more explicit.
Agreed. The text should make a clear statement, and I guess the schema
should be updated as well.
