The "<prefix>" and "<suffix>" in the example in doc (I assume you are
talking about this one: [‹prefix› + someExpression + ‹suffix›/]) is just
to indicate that they are placeholder for actual string expressions. The
"<" and ">" symbols are not part of the syntax.

Acceleo extends OCL, so it uses the same syntax for most things,
including strings. Literal strings are enclosed in single quotes.
I just re-tested it, and this syntax works fine:
[firstName + ' ' + lastName/]

The "+" operator is just a shorthand for this (like in Java).

You must have the Acceleo 3 support plug-ins installed, but that should
be the case in most situations. If you have
org.eclipse.sirius.common.acceleo.mtl.ide, you have everything you need.
