How to Tag a Caption with a Label

Question

Hello! I'm tagging a document to make it accessible, and it contains a figure with a caption that both labels the figure and contains standalone text. For example, "Figure 2. This is the caption of the above figure." The PDF assocation Tagged PDF Best Practice Guide: Syntax states: "In tagged PDF, elements are not limited to lists, and are always explicitly contained. structure elements may be used whenever content serves as a label for some other content, for example, “Fig: 123” in a caption for a

." This and other guidance make me think that tagging such a caption as stated (a caption parent tag for the whole caption with a label child tag for the labelling text such as "Figure 2") would be best practice. However, I can't find guidance on how to correctly create such a tag structure in Acrobat Pro DC, or what the corresponding container structure as viewed in the content panel should look like. Another accessibility requirement is that the caption for a figure element must follow the figure tag, rather than be a child of the figure tag. (This is because the figure alt text will override the caption text, making the text of the caption inaccessible to a screen reader.) I'm pretty sure most of my attempts so far have been incorrect, as the accessibility checker throws a list error for every configuration I've tried. How can you correctly create a caption tag with a child label tag in Acrobat Pro?
