Table Header Cell Element Name
Holds the name for the <th> element in NISO JATS tables.
The NISO JATS table model provides (as did the XHTML 1.1 table model on which it is based) a .qname parameter entity that provides the qualified name of each element, so the name can be easily customized with and without namespaces. 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: the separator character is a period, not a hyphen.
