Having seen the discussion on the users list recently, I fear that this issue 
will never go away and will never be satisfactorily implemented for the WP 
die-hards. 
 
At each point in the text of a document, the appearance is defined by a _set_ 
of attributes (font, colour, language, margins, indentation, background colour 
etc.) 
 
As I understand it from the comments made, reveal codes indicate how this set 
is built up by applying them from some default by processing the text from the 
beginning of the document. 
 
In a style-oriented writer, the set of attributes is built up by following the 
definitions of a style along its parent derivation tree from some default at 
its root. In effect, each character is given the _whole_set_ of attributes at 
the _same_time_, and that set is called its style (simplifying wildly). 
 
These two approaches are so different, that just writing a translator from one 
form to the other must be a challenging exercise. Asking either to look like 
the other in the GUI seems inappropriate if not actually technically 
infeasible. 
 
I can see the way that people are using reveal codes, and that imported text 
can mess things up, and so there is a need to see where an attribute last 
appeared. The equivalent in OOo would be to discover where in the style tree a 
particular attribute was last given its value. The current values can be seen 
by looking at the current style definition, but it is not easy to check up the 
tree for a given attribute (say language, or italic, etc.) But the need would 
be for a tree description _per_attribute_; trying to show it for all 
attributes simultaneously would be an excessive amount of information. An 
alternative would be to have on all tabs in the style dialogs a button that 
jumped immediately to the parent so the differences can be seen. 
 
I am not an OOo developer so what I say should be taken with the appropriate 
grain of salt. But my guess is that trying to display anything resembling 
reveal codes is not worth the effort that would have to be put into it, and 
will be a drain on maintenance activity and testing forever. But an 
improvement in the dialogs showing how an attribute came to be applied by 
explicitly displaying the tree might be possible. 
 
Please correct any misconceptions I might have.
