Hard to figure out when options are missing

[damonfeldman]

When options are missing or malformed (or in the wrong database) it would be helpful to say so explicitly. For debugging I've added this code into .../survivorship/merging/base.xqy at line 1844:

declare function merge-impl:get-options($options-name, $format as xs:string)
{
let $opt-uri := $MERGING-OPTIONS-DIR||$options-name||".xml"
let $options-doc := fn:doc($opt-uri)
let $options := $options-doc/merging:options
let $check :=
if (empty($options-doc)) then
(xdmp:log("no options doc:"||$opt-uri),
fn:error(xs:QName("SM-MISSING-CONFIG"), "no options doc found at URI '" || $opt-uri || "' in database: " || xdmp:database-name(xdmp:database()))
)
else if (empty($options)) then
(xdmp:log("no options node in options doc at "||$opt-uri),
fn:error(xs:QName("SM-MISSING-CONFIG"), "no merging:options node found at root of doc(" || $opt-uri || ") in database: " || xdmp:database-name(xdmp:database()))
)
else
(xdmp:log("no problem getting config"))

which does explicit checks and returns a (new) error code when options are missing or malformed, including the URI and DB being checked.
