What is the difference between :raw-value and :title?

What is the difference between :raw-value and :title?

[mbork]

Hi all,

I am reading the Org element API docs and I don't understand the
difference between :raw-value of a headline and its :title.  I performed
a few experiments with putting various things in the headline
(timestamps, links, markup) to find a case where these two differ, but I
could not.

The :title is described as a "secondary string".  What is a "secondary
string"?  Maybe if I knew that, I would understand the difference...?

TIA,

Check out "secondary nodes" in lisp/org-element-ast.el comment.

TL;DR: Secondary string is a parsed Org markup, as an "anonymous node"
(list of Org markup objects).

For headings, things are a little tricky though - while :raw-title
always contain unparsed "raw" title text, :title may, depending on the
parser mode, either be a copy of :raw-title or contain the parsed
secondary string.
