Using lists in hrl to create wsdl errors

[hez]

Using part of the example from https://github.com/bet365/soap/blob/master/doc/generating_a_wsdl.md

-spec store(Parsed_body::#person{},
    Soap_req::soap:soap_req(), State::soap:soap_handler_state())
    -> soap:soap_handler_response(contacts_response()).

-record(person, {
        '@id' :: integer(),          %% will be an attribute "id" in the XML
        first_name :: string(),
        last_name = "" :: string(),  %% will mandatory in the XSD
        married :: boolean(),
        age :: non_neg_integer(),
        height :: float(),
        hobbies :: [string()]
}).

-type person() :: #person{}.

errors with

1> soap:erlang2wsdl("contacts.hrl", "contacts", "http://localhost:8080").
** exception throw: {error,"Wrong Type in attribute type, expected qname, got {{qname,\"http://www.w3.org/2001/XMLSchema\",\"string\",undefined,undefined},\n undefined,undefined}"}
