[DEPRECATED: use xdmp:eval with the database option instead] Returns the result of evaluating a string as an XQuery module in a given database.

Parameters
xquery	The XQuery string to be evaluated. If the XQuery string contains double quotes ("), surround the string with single quotes (').
ID	The database ID, from `xdmp:database("db_name")`, `xdmp:security-database()`, or `xdmp:schema-database()`.
vars	The external variable values for this evaluation. This must be a sequence of even length, alternating QNames and items. Each QName and item pair specify a variable name and value.
modules	The modules database for processing module imports. The empty sequence specifies the current modules database.
root	The root path for modules. The empty sequence specifies the current root.
