<caption> – figure/table captionxml:langidstyle/classPossible Contents: (Text | inline element)*
Description:
The caption of a float object or the origin of an aphorism. If you use
it within a float, i.e. a <figure> or a <table>, you
can leave it empty; in this case the float only gets a number. It
doesn't get a number just because it has an id!
