Robert,
 the value of the enc:itemType AII is a type name that will be
assigned to the array items should they not specify their type
names using xsi:type. It is assumed (though not required) that 
the type names will be the names of types (simple or complex) 
defined using XML Schema. Therefore I don't believe you can have 
square brackets in there because (IIRC) they are not allowed in 
an XML Schema type name.
 One can define a two-dimensional array in XML Schema by
restricting the enc:Array type so that the arraySize attribute
has exactly two parts (as opposed to any number). And IMHO this
should be the only way two-or-more-dimensional SOAP-Encoding
arrays are defined in XML Schema.
 Then you can give this type a name, anything like
"2dArrayOfFoo", "ArrayOfFoo", "Bar" or other. The name should not 
play any role in distinguishing arrays from other types.
 It is my opinion that using XML Schema to describe data in the
SOAP Data Model is flawed (XML Schema's data model being
different; one cannot easily combine data models), but apparently
enough "common understanding of hacks" exists for this to be
viable.
 Oh, I have to add (just in case it's not clear) that a
two-dimensional array is a different beast from an array of 
arrays. Java doesn't have multidimensional arrays, C/C++ does.
 Best regards,
