That seems wrong, because the right side of the pipe may be omitted completely. The correct syntax would then be (formatted for better readability):
[
<offset-position> |
<offset-path> [ <offset-distance> || <offset-rotation> ]? |
<offset-position> <offset-path> [ <offset-distance> || <offset-rotation> ]?
] [ / <offset-anchor> ]?
This makes the definition a bit long, so I can understand that @fantasai wants to add a new combinator. If one is to be created, I think it would look better like this, though:
[ <offset-position> ?! [ <offset-path> [ <offset-distance> || <offset-rotation> ]? ] ]
[ / <offset-anchor> ]?
or to use `?!` as a multiplier:
[ <offset-position>?! [ <offset-path> [ <offset-distance> || <offset-rotation> ]? ]?! ]
[ / <offset-anchor> ]?
