OFFICE-3768 empty cell proposal for section 4.7

[Regina Henschel <regina.henschel@libreoffice.org>]

Hi all,

what do you think about the proposal below?

I'm not sure about child elements <text:h>. LibreOffice does not create 
such child element in a spreadsheet. When reading a file or copy&paste a 
table from a text document, LibreOffice treats an <text:h> element same 
as an <text:p> element and saves it as <text:p> element.

Kind regards
Regin


Proposal
========
4.7 empty cell
The technical term "empty cell" is used in this part of the 
specification in defining functions and expressions. The technical term 
"empty cell" stands for a cell, for which non of the following 
properties is true:
    The cell has a table:formula attribute.
    The cell has a <text:p> child element.
    The cell has an office:value-type attribute and the corresponding 
value attribute office:value, office:date-value, office:time-value, 
office:boolean-value, or office:string-value, respectively.

Note:
The markup <table:table-cell><text:p/></table:table-cell> generates no 
"empty cell" but a cell containing an empty string.
