I changed the normative language to read: The table:search-criteria-must-apply-to-whole-cell attribute specifies whether a search pattern matches the entire content of a cell. The defined values for the table:search-criteria-must-apply-to-whole-cell are: false: search pattern must match entire content of a cell.. true: search pattern can match a substring at any position within a cell.. (I then added the other material Eike suggested as a non-normative note. It wasn't clear if this was a requirement or simply an observation on the use of the attribute.) Note: The table:search-criteria-must-apply-to-whole-cell is used with the <table:filter-condition> element when the table:data-type attribute has the value text and the table:operator attribute has a value of: match, !match, =, or !=.
