(1) I think, the central idea is in the note in section "9.1.1 General",
"Note: There is only one model for tables, although tables, such as for
spreadsheets, may have additional capabilities when compared to tables in text
That means, that cell attributes, formula included, are treaded the same in
Writer and Calc. Historically LibreOffice uses different syntax for formulas in
Writer and Calc, but that is not a demand of the specification.

(2) If you use a <text:expression> element, then it is child of a <text:p>
element in the content of a cell. That adds two levels nesting to access the

(3) Each cell has a type, defined by the office:value-type attribute and a
value, defined by one of the office:value, office:boolean-value,
office:string-value,... attributes. Only in case of office:value-type="string"
and missing office:string-value attribute the cell content itself is the
"value" of the cell.

The <text:expression> element is child of a <text:p> element in the content of
a cell. The content of the cell can only be "value" of the cell, if the cell is
of type string. But if it is a string, you cannot calculate with the value, at
least not with the Writer formula syntax, which does not know any
string-functions. If you provided an automatic conversion, you would get all
the problems of text->number conversion and its language dependency known from

(4) The office:value is faulty in <text:expression> in current implementation.
Its value is always 0 but should be the result of the formula.=> bug 111674
