Trouble sending messages to Dynamics AX: Element is not declared.

Question

I'm having problems getting Dynamics AX to accept a message from BizTalk.
Here's my setup:
AX 2012:
A table, BTAIF_test, with two fields ("Name" and "Phone").
A query, BTAIFQuery, with BTAIF_test as datasource.
A service, BTAIFQueryService, autogenerated by the AX AIF Wizard, registered and deployed on
An inbound port, BTAIF, using net.tcp.
BizTalk:
An incoming schema, generated from a simple XML file containing a name and a phone number.
An outgoing schema, generated by the Consume WCF Service wizard.
A map, mapping the two value fields from the incoming to the outgoing schema.
A receive port, using a receive location with FILE transport to pick up the incoming message, and using XMLReceive pipeline
A send port, using the previously mentioned map, and WCF-NetTcp configured with my AX service address and a simple soap header pointing at the create method of the service. It uses the XMLTransmit pipeline.
When I drop a message in the receive location I get the following message in the Exception log of AX:
"Invalid document schema. The following error was returned:  
The 'http://schemas.microsoft.com/dynamics/2008/01/documents/BTAIFQuery:BTAIFtest_1' element is not declared."
The send port has a backup FILE transport, and this is what the message looks like when it dumps it there:
<?xml version="1.0" encoding="utf-8"?>
<ns0:BTAIFQuery xmlns:ns0="http://schemas.microsoft.com/dynamics/2008/01/documents/BTAIFQuery"
xmlns:st="http://schemas.microsoft.com/dynamics/2008/01/sharedtypes">
<ns0:BTAIFtest_1 class="entity">
<ns0:Name>John Hancock</ns0:Name>
<ns0:Phone>555-123-4567</ns0:Phone>
</ns0:BTAIFtest_1>
</ns0:BTAIFQuery>
Any pointers as to what I'm doing wrong here? I've been searching for information on the net and either nobody's doing this or it's so easy nobody cares to write about it. I'm hoping it's the latter and I'm just making some stupid mistake.

From the above output I think the AxdExtType_Name, AxdExtType_Phone and AxdEnum_AxdEntityAction are defined as simple type in BTAIF_schemas_microsoft_com_dynamics_2008_01_sharedtypes.xsd, so the above output is correct as per this schema. Recheck if the
format of schema is correct so that AX can accept it.
Yes, they're defined as simple types, here's the relevant definitions from sharedtypes.xsd:
<xs:simpleType name="AxdExtType_Name">
<xs:annotation>
<xs:documentation xml:lang="EN-US">Name:Name.</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:string">
<xs:minLength value="0" />
<xs:maxLength value="60" />
</xs:restriction>
</xs:simpleType>
<xs:simpleType name="AxdExtType_Phone">
<xs:annotation>
<xs:documentation xml:lang="EN-US">Telephone:Telephone number.</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:string">
<xs:minLength value="0" />
<xs:maxLength value="20" />
</xs:restriction>
</xs:simpleType>
<xs:simpleType name="AxdEnum_AxdEntityAction">
<xs:annotation>
<xs:documentation xml:lang="EN-US">AxdEntityAction:AxdEntityAction</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:string">
<xs:enumeration value="create" />
<xs:enumeration value="update" />
<xs:enumeration value="replace" />
<xs:enumeration value="delete" />
</xs:restriction>
</xs:simpleType>
This schema and the destination schemas are auto-generated by BizTalk's Consume WCF Service
wizard.
