QuickFIX/n and FXALL - quickfix

Question

I am trying to send a MarketDataRequest to FXAll FIX Server using FIX 4.3 standard. Looking at the documentation the response from the server should be as follow
<message name="MarketDataIncrementalRefresh" msgtype="X" msgcat="app">
<field name="MDReqID" required="N" />
<group name="NoMDEntries" required="Y">
<field name="MDUpdateAction" required="Y" />
<field name="DeleteReason" required="N" />
<field name="MDEntryType" required="N" />
<field name="MDEntryID" required="N" />
<field name="MDEntryRefID" required="N" />
<component name="Instrument" required="N" />
<field name="FinancialStatus" required="N" />
<field name="CorporateAction" required="N" />
... omissis ...
</group>
</message>
but in the FXAll API Documentation field 55 (Instrument o Symbol) is expected just after the field MDReqID like it should be on the standard MarketDataSnapshotFullRefresh message
<message name="MarketDataSnapshotFullRefresh" msgtype="W" msgcat="app">
<field name="MDReqID" required="N" />
<component name="Instrument" required="Y" />
... omissis ...
</message>
Of course QuickFix/n engine is trapping a message MarketDataIncrementalRefresh with the field msgtype="X" and then I always have a TagNotDefinedForMessage error. How to solve this problem?
Thank in advance.

We modified our FIX43.xml file to FIX43_FXALL.xml and specific in the quickfix config file that we wanted to use that specific data dictionary (ie we used the direct path the file).
The modification looked like this:

<field name="MDReqID" required="N" />
<component name="Instrument" required="Y" />
<group name="NoMDEntries" required="Y">
<field name="MDUpdateAction" required="Y" />
<field name="MDEntryType" required="Y" />
<field name="MDEntryID" required="Y" />
