Ultimately both should work - Being able to link to a point in
another entity is necessary if parametrics and restraints are going
to be supported.
ie. carry on storing points as vectors/coordinates inside the
element:
points:
-
- 10.3
- 3.0
- -6.3
-
- 2.0
- 3.5
- 6.9
..but later have a syntax for addressing a point in another element:
points:
-
- 10.3
- 3.0
- -6.3
- ref#10.yml/points/5
Programmers can use the 'reference' method entirely for a particular
application if they need it.
