Ok. In AX2009, data from a table cannot be directly exported via XML, you need a special intermediary class called AxYourTableName. Only the fields represented by the parmYourFieldName methods may be exported.

For a simple example, take a look at \Classes\AxCustGroup

AFAIK, the AIF class wizard is able to generate an Ax-Class automatically.

See http://msdn.microsoft.com/en-us/library/aa873749.aspx

By the way, an AX-class with an AXD-class are still not sufficient. You additionally need an AXD-query, which is pretty easy to build.
