The style:cell-protect property specifies how a cell is protected. This attribute is only evaluated if the current table is protected (see section 8.1.1). The value of the attribute can be "none", "hidden-and-protected", or a space-separated list containing the values "protected" or "formula-hidden".

the expected behavior in the text is:

• the text in the first cell is not protected.
• the text in the second cell is protected and read only.
• the text in the third cell is not protected.
• the text in the fourth cell is protected and read only.

big change in open office application, the style:cell-protect property in table-cell style can't fulfill this function. However, set table:protected="true" directly in table:table-cell attlist can set the corresponding cell read only. the contradictions here are not only in this section(15.11.14 Cell Protect) but also in table protected section (8.1.1 Table Element).

In (8.1.1 Table Element), it is said that The table:protected attribute specifies whether or not a table is protected from editing. If the table is protected, the table:protection-key attribute can specify a password to prevent a user from resetting the protection flag to enable editing. If a table is protected, all of the table elements and the cell elements with a style:cell-protect attribute set to true are protected.
