Selects which frame rules are enabled. Possible values are:

  • None — frame rules are disabled;

  • Top — enable top rule only;

  • Bottom — enable bottom rule only;

  • TopBot — enable top and bottom rules;

  • Sides — enable left and right rules;

  • All — enable all frame rules (the default).

It is important to note that a frame rule will not appear unless it is specified in the CALS or HTML markup. The Mask allows you to suppress these rules for a particular print run, but will not force a rule to appear if the markup does not specify a frame in the first place. This means that a frame rule will only appear if it is specified in the markup and enabled in the mask.

Use the <table-properties frame="TYPE" /> directive if you need to assign the state of the implied table frame.
