+              <!-- 2020-02-13 ebb: During today's release, we did the following somewhat problematic steps to generate the plugin. 
+                1) Generate a zip file using the ant instructions above.
+                2) Make a release on the tei-oxygen GitHub repo, and attach the zip file to it.
+                NOTE: We could not add this to the tei-c.org server according to the posted instructions here . 
+                So we "did this by hand" as the tei-user logging in as we did to post the Guidelines and Stylesheets release files to the Vault.
