%th.element;
Table Header Cell Element Control For a Table
This parameter entity holds the INCLUDE or IGNORE keyword to control a conditional
marked section, that determines whether the Table Header Cell (NISO JATS table model)
element is defined for NISO JATS tables.
Remarks
The NISO JATS table model parameter entity is used in the same way as the equivalent
parameter entity in the XHTML 1.1 table model. Since this parameter entity was named
in the same way as the XHTML 1.1 Tag Set equivalent, it does not follow
the naming conventions for this Tag Set: it is in mixed not lower case, and the
separator character is a period, not a hyphen.
