| By "official syntax" you mean the Spad/Axiom language standard?

newline has been part of OpenAxiom since November 2010 (therefore part
of OpenAxiom-1.4.0). You can use it (and other character constants) in
both the library and the interpreter. It is a constant, so you can
just write
newline
without the '()'. It (or char "\n") has been used in other projects
such as Arthur's server.
The character constants are available from the Hyperdoc, therefore reachable
from "Browse".
