What I have in mind is to modify `org-export-read-attribute' directly.
Then, we can call `org-export-read-attribute' in `org-export-data';
resolve the refs in the template (re-use code from
`org-babel-ref-resolve' and `org-babel-parse-multiple-vars'); do normal
export and pass it to the template. Before running the normal export, we
strip :export_template from the INFO to avoid issues with ox-html which
puts every single attr into the generated html.
