==Simple==

{{#invoke:Arraymap |map 
|vals=Álvar,Núñez ,, Cabeza,de Vaca,,|sep=,,
|varstr=xxx |map=(xxx) |outputsep=;\s
}}

[Álvar];\s[Núñez];\s[Cabeza];\s[de Vaca]

Or, using unnamed, sequential approach:

{{#invoke:Arraymap |map |Álvar,Núñez ,, Cabeza, de Vaca,, |, |xxx |[xxx] |;\s}}

[Álvar];\s[Núñez];\s[Cabeza];\s[de Vaca]

Special use cases

If sep needs to be a space, use %s?

Escaped syntax for curly braces and pipes

Escape {{... }} as %{%{ ...  %}%}
Escape | as %

{{#invoke:Arraymap |map
|vals=Persoon/-1002367743,Persoon/400
|sep=,
|varstr=xxx
|map=%{%{#ask: [[xxx]] %mainlabel=- %?Has name= %}%} 
|outputsep=;\s
|escaped=true
|fuzzy=false
}}

%{%{#ask: Nelly Kruize %mainlabel=- %?Has name= %}%};\s%{%{#ask: Ralph Blum %mainlabel=- %?Has name= %}%}
