The function wizard tells, that the second parameter (Database field) is required, but it is optional, see 70806. And with ODF 1.3 this is standard. The text in the function wizard needs to be adapted. The help is already correct.

took some time to spot it, have a cell with DCOUNT[A] formula, set focus on it, click formula wizard right to 'name box', click into the formula shown in the box 'Formula' bottom right of the wizard dialog, place cursor on the second parameter, comment above says 'Database field (required)',
is like that at already in ver. 188.8.131.52, inherited?
i could add that the function doesn't count the 'cells' in the range but the rows or datasets?
and that 'Indicates which database field (column) is to be used for the search criteria' is also questionable, on a first view the search criteria is applied by matching the headers of the 'Database' and 'search criteria' definition, while the 'Database field' parameter - if given - restricts the result to rows (datasets) in which the column it indicates evaluates to a numerical value,
