Sure.  I have added a function to org-export-filter-parse-tree-functions
which replaces a custom keyword with either a latex-fragment or an HTML
link wrapped in a paragraph depending on the export backend.  The latex
fragment basically has the following content,

    "\\begin{figure}
      \\centering
      \\input{%s}
      \\caption[%s]{\\label{%s}%s}
    \\end{figure}\n\n"

and I assign it a :name property to match the label in the above.  I
then have links elsewhere in the file which reference this label.

Is there a better way to achieve output like the above?  If not I think
an argument can be made that either (1) after filters have run
assumptions about which types can support which properties are moot, or
(2) there should be a way to have a filter insert a named chunk of
backend-specific code.

Thanks,
Eric
