[MarkLogic Dev General] External variables and HTTP app server

[David Sewell]

Is there any way to pass an external variable to the main query when it
is running via an HTTP app server? I.e., making it possible to run

   define variable $x as xs:string external

   $x

without throwing an "undefined external variable error"?

(I know I can use HTTP request fields to pass "external variables". But
I have some code I'd like to be able to run without modification via
XDBC, which returns () for xdmp:get-request-field(), etc. So is there
any  mechanism of passing a run-time external variable to the
server that works the same way under either HTTP or XDBC app servers?)
