Additional attributes should be used throughout the NISO JATS table model by way of the %xhtml-inlstyle-1.mod; module
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.
