Yes it is. Here is how to do it:

To build a SOAP_Array you need first to build an Object_Set. The SOAP_Array
construction is SOAP.Types.A.

So in your case you need to declare something like:

   Items : Object_Set (1 .. Max_Results);

Now, every Item is an Object_Safe_Pointer. You build such type using the "+"
function on an Object'Class. Every SOAP types are derived from
SOAP.Types.Object. For example:

   Items (1) := +I (12, "int_value");

You said you know how to build a SOAP_Record. Let's say that My_Record is one
of your SOAP_Record:

   Items (2) := +My_Record;

Last step is to build the array:

   My_Array : constant SOAP_Array := A (Items, "my_array");

(All this has not been compiled, I hope there is no typos).

Let me know if this is not clear.

Note that AWS 1.4 will have a WSDL parser/generator, all this will be
transparent. wsdl2aws is a tool that takes a WSDL document and generate all
the code needed to call the Web Service or to build the Web Service server.

Pascal.
