<block-alternatives> Block-level Alternatives
Container element to hold block-level processing alternatives, such as the same table
or figure in two languages.
Usage/Remarks
The major use case for <block-alternatives> is multiple versions, probably multiple language versions, of a block-level assemblage
such as a table or boxed-text. For example, a typical use case is an article in a
printed journal which contains a figure in Portuguese and the same article when presented
online with that figure in English (identical figures). Use cases include a figure provided
as alternatives two or three times for a single output format (one figure in each
language) and of one table provided as alternatives two or three times (one table
in each language).
Comparison to Figure Group
A group of identical figures is not a figure group. The element <fig-group> is defined as a collection of related figures, rather than multiples of the same figure. A figure group containing 6 figures
counts as 6 figures; a <block-alternatives> element containing 6 figures would count as a single figure, with 6 processing alternatives.
Not for Article Structures
JATS does not allow alternatives to document structures such as appendices and appendix
groups. Therefore <app> and similar structural elements (as opposed to block-level elements) are not allowed
inside <block-alternatives>.
