[ODF 1.2] Comment missing, whether error values are propagated

Hello members,

this is a comment to part 2.
In 4.6 you find, "Functions and operators that receive one or more error 
values as an input shall produce one of those input error values as 
their result, except when the formula or operator is specifically 
defined to do otherwise."
Such "specifically defined" is done in function 6.13.6 COUNT, "Errors 
are not propagated." for example.

The functions ISBLANK, ISERR, ISERROR, ISFORMULA (not in Excel), 
ISLOGICAL, ISNA, ISNONTEXT, ISNUMBER, ISREF, ISTEXT, and TYPE do not 
propagate an error in OOo, LibO, Gnumeric, and Excel.

The functions ISEVEN and ISODD propagate an error value in OOo, LibO, 
Gnumeric and Excel.

The functions ISERR and ISERROR and ISNA have the comment, "Note that 
this function does not propagate Error values." The functions ISBLANK, 
ISFORMULA, ISLOGICAL, ISNONTEXT, ISNUMBER, ISREF, ISTEXT, and TYPE do 
not have such a comment. They should get such a comment too. Having no 
such comment leads to confusions like
