// Discover whether array can be serialized directly as a two-dimensional

// - Less text passed on the wire.
// - Easier to read wire format
// - Tests the deserialization of multi-dimensional arrays.
// Drawbacks:
// - Is not safe! It is possible that the arrays are multiply
// referenced. Transforming into a 2-dim array will cause the
// multi-referenced information to be lost. Plus there is no
// way to determine whether the arrays are multi-referenced.
// - .NET currently (Dec 2002) does not support 2D SOAP-encoded arrays
//
// OLD Comment as to why this was ENABLED:
// It is necessary for
// interoperability (echo2DStringArray). It is 'safe' for now
// because Axis treats arrays as non multi-ref (see the note
// in SerializationContext.isPrimitive(...) )
// More complicated processing is necessary for 3-dim arrays, etc.
//
// Axis 1.1 - December 2002
// Turned this OFF because Microsoft .NET can not deserialize
// multi-dimensional SOAP-encoded arrays, and this interopability
// is pretty high visibility. Make it a global configuration parameter:
// <parameter name="enable2DArrayEncoding" value="true"/> (tomj)
