It is simpler.
Everything after the bullet and before the last " :: " is considered as
tag. Everything after the last " :: " is description.
Then, tag and description are parsed, allowing objects inside.

org-syntax document is inaccurate here - it says that the _first_ " :: "
is used as tag:description delimiter, not the _last_.

I do not see any benefit changing the current parser. So, we probably
need to update org-syntax document instead.
