%etal-model;
Et Al Content Model
The content model for the <etal> element
Remarks
Many tag sets model the <etal> element as EMPTY, meaning that the element has no content. Such an empty element is typically used as a place holder, for example, to generate the text “et al.” via a stylesheet. In this Tag Set, the element is typically used as an empty element, but this Tag Set also accommodates those journal tag sets that expect content inside <etal>, so the element is modeled with text content instead of as formally EMPTY and may contain text such as “Associates, co-workers, and colleagues”.
