expr.init.[Var]

Use this property to contain variables that are longer Erlang terms, such as maps #{...}, and lists [...].

The expr.init property is appended with the name of the variable.
<service 
  name="Database" provision="expr">
  <prop 
    name="expr.init.Table"
    content-type="text/x-erlang"><![CDATA[
#{
  0 => "Foo",
  1 => "Bar"}
  ]]></prop>
</service>
Important: Do not use a full stop at the end of the term, like in the case of expressions contained in expr.src.
Tip: To get syntax highlighting, use the content-type="text/x-erlang" attribute.
