Possible to get current user's account SID in Wix?

Question

In our installer, we pass a unique local account identifier on a service's command line, e.g.

<ServiceInstall ...
                Arguments="[LogonUser]"
                ... />

I'm considering passing the current user's account SID (e.g. S-1-5-21-4291167501-1931063052-1968030807-1001) instead.

I inherited this installer, and I'm very new to Wix. Does anyone know whether the SID is available, or how I might retrieve it?

You can use the UserSID built-in property.
