dbg functions

The table below lists all the dbg built-in functions (in this namespace: http://marklogic.com/xdmp/debug).

Implements a library of functions which allow developers to build an IDE which will allow runtime debugging of query requests against MarkLogic Server. The debug functions allow you to build an application that does things like attach to a running server, set breakpoints in a query, examine the value of variables at a point in query execution, and so on. Note that the debug function library is not a debugger, but provides server-side support to build an application that can debug queries against MarkLogic Server.
