The "parser.allows.dash.identifiers" mention is a reference to a long
disappeared name for this property.
The property name is "parser.allow_hyphen_in_identifiers", and it's a hyphen,
we're all good.
[~calvernaz] Thanks for catching this documentation glitch!

> Regarding the use of hypens on identifiers, the documentation doesn't look
> consistent. Which one is recommended?
> [Here|https://velocity.apache.org/engine/2.3/configuration.html] states the
> following:
> *{{parser.allow_hyphen_in_identifiers = false}}*
> {quote}This is a backward compatibility option, false by default, which
> allows the '{*}{{-}}{*}' character inside variable identifiers (available
> since 2.1). If enabled, be warned that you will have to surround the
> mathematical minus sign with spaces for it to be correctly interpreted.
> {quote}
>
> But [here|https://velocity.apache.org/engine/2.3/vtl-reference.html], the
> configuration is different:
> {quote}{{If the *parser.allows.dash.identifiers*}} configuration value is set
> to true, then the *-* dash is also allowed in identifiers (and must be
> surrounded by spaces to be interpreted as an arithmetic minus operator).}}
> {quote}
