Hi Charles,

I used your minimal example to show the issue I am seeing when using
ox-md as the base exporter.

=====
#+property: header-args :results none :exports none :eval never-export
#+options: toc:nil

* Define newmd                                                     :noexport:
Eval below to define a minimal "newmd" exporter:
#+begin_src emacs-lisp
;; minimal backend with md parent
(org-export-define-derived-backend 'newmd 'md
  :translate-alist
  '((special-block . org-newmd-special-block)))

;; special block transcoder
(defun org-newmd-special-block (special-block contents info)
  "Newmd special block transcoder."
  (let
       ((type (org-element-property :type special-block)))
    (if (equal type "katex")
        (format "{{<%s>}}\n%s{{<//%s>}}\n" type contents type)
      ;; not `katex' so default to md transcoder
      (org-export-with-backend 'md special-block contents info))))
#+end_src
* Test block for exporting
#+begin_katex
E = -J \sum_{i=1}^N s_i s_{i+1}
#+end_katex
* Do export                                                        :noexport:
Eval below to export this buffer using the ~newmd~ exporter:
#+begin_src emacs-lisp
(org-export-to-buffer 'newmd "*Org NEW LATEX Export*" nil nil nil :body-only)
#+end_src
=====

1. Eval the block in first heading
2. Eval the block in second heading to export

Exporter buffer content:

=====
# Test block for exporting

{{<katex>}}
E = -J &sum;<sub>i=1</sub>^N s\_i s<sub>i+1</sub>
{{<//katex>}}
=====


How do we disable Org from transforming this:

    E = -J \sum_{i=1}^N s_i s_{i+1}

to this:


    E = -J &sum;<sub>i=1</sub>^N s\_i s<sub>i+1</sub>
