%title-elements;
Elements Used in Titles
Elements that can be mixed with the data characters inside the various title elements, for example, inside <title>, <subtitle>, <trans-title>, etc.
Remarks
Historical Note: In earlier versions of this Tag Set, this parameter entity was
used directly with the elements names above. However, in the current Tag Set, unnecessary dependencies have been removed; each element was given its own element-naming parameter entity. In the default case, these call this parameter entity for backwards compatibility.
