In the final solutions the sequence diagram supports descriptions, line breaks, links, ... of all elements.
The only main difference are
a) boundaries have to be defined without { and } and instead of } the Boundary_End() macro has to be called
b) descriptions of the elements (person, system,... ) are deactivated; they can be activated via the layout option SHOW_ELEMENT_DESCRIPTIONS(?show)
c) in contrast to a normal sequence diagram the foot boxes are deactivated; they can be activated via SHOW_FOOT_BOXES(?show)
The C4 language itself is basically not extended, missing new features like Grouping messages have to added with native PlantUML syntax.
I have no useful sample at the moment, maybe someone can attach a more practical sample
(part of the new docu)
(C4 styled) Sequence diagram
C4-PlantUML does not offer a full sequence diagram support,
but existing elements and relationships can be reused as participants and calls in the corresponding styles.
!!! Contrary to all other diagrams, please define boundaries without { and } and mark a boundary end with Boundary_End() !!!
RelSpecialIndex($rel, $e_index, $from, $to, $label, $techn="", $descr="", $sprite="", $tags="", $link=""):
$rel enables the definition of all PlantUML specific arrow types, details see e.g.
All arrow types and
Slanted or odd arrows
The 5 index related macros (like the dynamic diagram)
(lowercase) increment($offset=1): increase current index (procedure which has no direct output)
(lowercase) setIndex($new_index): set the new index (procedure which has no direct output)
LastIndex(): return the last used index (function which can be used as argument)
Index($offset=1): returns current index and calculates next index (function which can be used as argument)
SetIndex($new_index): returns new set index and calculates next index (function which can be used as argument)

Themes supports sequence diagrams too (details see new section in Themes.md)
It can be tested via my extended branch
