@sbgn-editors: Please see if you like this suggestion for a new page.
Denis Shirshov who works on the PD2AF converter has asked if there is a way to quickly refer to any SBGN element via separate URI or URL. I think it would be useful to have that. It could be sort of a mini-specification, a short version for students with very minimal information.
Now we have the Symbol Highlight page but I guess it does not cover all glyphs for all languages. Does it cover all PD glyphs?
Reference could look like this:
