Wells Fargo Investment Account

Does anybody know what account type to use for an investment account?
for example SAVINGS, CHECKING, ???

OR should I use different OFX syntax since it is an investment account? something like this maybe?

    <INVSTMTMSGSRQV1>
        <INVSTMTTRNRQ>
            <TRNUID>${TRANS_ID}
            <INVSTMTRQ>
                <INVACCTFROM>
                    <BROKERID>wellsfargo.com
                    <ACCTID>${ACCT_ID}
                </INVACCTFROM>
                <INCTRAN>
                    <DTSTART>${START_DATE}</DTSTART>
                    <DTEND>${END_DATE}</DTEND>
                    <INCLUDE>Y
                </INCTRAN>
                <INCOO>N
                <INCPOS>N
                <INCBAL>Y
            </INVSTMTRQ>
        </INVSTMTTRNRQ>
    </INVSTMTMSGSRQV1>

Any help appreciated.
