tdf#69569 ODFFv1.2 part 2 incorrect

Hi Eike,

I have been studying ODFFv1.2 part 2 §4.11.7.7 with 
https://bugs.documentfoundation.org/show_bug.cgi?id=69569#c17 , lines 1..5. in mind.

My conclusions are that
a) Line 8 should be
    " 8.Otherwise, if _(not A)_ and is-leap-year(year(date1)) then return 366 ";
b) Lines 9 and 10 can be combined by appending inclusive to both dates, the current line 9 is 
ambiguous and line 10 does not fully solve that;
c) The constraint date1 >= date2 is missing in §4.11.7. 

I have made logical diagrams to cheack that all possible combinations of date1 and date2 are 
covered - on the presumption that date1 >= date2.
If you agree with my conclusions, would it be possible that you submit a proposal for changing ODFF 
to reflect the above? 
I think that a proposal from you is more effective than one from me ;-)

And if you agree with my conclusions I intend to work on bug tdf69569 to implement the proposed 
changes (c is already implemented in /core/scaddins/source.analysis/analysishelper.cxx, 
getYearFrac(.)).
