18.104.22.168 Debug attribute group
The debug attributes group includes a set of debugging attributes that are normally hidden from authoring view. These attributes are defined for every DITA element.
These attributes are intended to store debugging information during intermediate processing.
One possible implementation is to use
@xtrf (xml-trace-filename) to store the
original source file name through intermediate processing steps, and use
xml-trace-counter) to store an element counter for repositioning authoring tools at the
originating element location. If values are assigned in this way in the first stage of a
processing stream, values in these attributes can then be used for error recovery.
