 : xco-debug - functions providing debug functionality

module namespace dg="http://www.parsqube.de/ns/xco/debug";

 : Inserts into the options map a 'debug' entry, which is a map
 : containing two keys:
 : 'dir' - the output folder into which debug files are written
 : 'filter' - a map associating debug ids with filter strings
 :
 : The 'debug' entry is evaluated by function db:WRITE_FILE. The
 : entry controls where and if a file is written.
 :
 : Example: 
 :    debugFilter: 5=PriceType, 7, 8=OrderElem
 :    debugDir: /projects/tmp
 :
 : 'debug' entry of options:
 :   debug:
 :       dir: /projects/tmp
 :       filter:
 :           5: 'PriceType'
 :           7: '*'
 :           8: 'OrderElem
