transcr.: what to do with "2nd degree stuff" (subst in note, subst in add, add in note, etc.)

[BOberreither]

Wherever handwritten additions (in note or add) have corrections themselves, they should be displayed according to their rend attribute:

note or add has subst rend above/below/inline/overwritten.
above/below: nested del: strikethrough inline; nested add: placed add/text() accordingly above or below - relative to the subst/del
inline: nested del: strikethrough inline; nested add placed right after
overwritten: make del text lighter and place add text right on it, like with overwritten in typescript pages

note or add has add rend above/below
above/below: place add/text() accordingly above or below - relative to the place of the add element's pipe symbol

note or add has metamark function insertion
place the note referred to by metamark according to its place attribute (not relative to any other element like above)
rend the metamark as a pipe symbol, link them by highlighting

Watch out: font size does not decrease like with add or subst in print/typescript! Stays 60-80% relative to print.
