In RTL (as well as TTB and BTT) the indentation will typically be in the 
reading direction.  

In future releases of Apache OpenOffice, the Chinese case is going to use 
double-character indentation when automatic indentation is specified in the 
paragraph style.  The change is also being made in LibreOffice, so there will 
be interchange compatibility.

Microsoft Office evidently has no automatic indentation, so there is nothing to 
coordinate there.  OpenOffice documents that are interchanged in .doc or .odt 
format will show up in  Microsoft Office Word with no indentation on those 
paragraphs specified to have automatic indentation in OpenOffice. 

The assumption with regard to legacy breakage of ODF document presentation is 
that there is little use of auto-indentation in existing Chinese ODF documents. 
 That is because that indentation does not satisfy the understood and 
widely-employed indentation style that would be honored in important documents.

This is now covered at <https://bz.apache.org/ooo/show_bug.cgi?id=126476>.

If anyone has a solid concrete objection to why this would be unacceptably 
breaking, we need to know that quickly before LibreOffice and OpenOffice 
reflect this change in distributed updates.

I cannot answer for what happens when using R to L type or what (if any) is the 
typesetting "norm" for such languages.  I'll root around later today to see if 
I can come up with anything, but I'm going offline shortly to do Saturday 
things.
