+Tuscany SDO for C++
+===================
+
+
+Tuscany SDO is an implmentation of the Service Data Objects 2.0 specification for C++ developers.
+
+The implmentation adheres closely to the specifcation, but there are a number of features which 
+did not make it into this release. These are documented below.
+
+
+Generic get/set
+===============
+
+The C++ implementation defines a set of access methods directly appropriate to each Type. For example
+getString(), setString(), getBoolean(), setBoolean(). There is no generic get() method as there is no
+common base object to return - unlike the java implementation which can return an Object.  
+
+Typesafe interface
+==================
+
+There is no code generation in this version, so there is no interface such that a property called
+"Name" can be accessed via object->getName().  The name must be accessed via object->getString("Name");
+
+Change Summary Serialization.
+=============================
+
+Change summaries contain creations, deletions and modifications to data graphs. The specification 
+indicates that these will be serialized to XML such that creations and deletions will become attributes
+of the change summary element, whilst changes become elements within the change summary element.
+This implementation saves all creations, deletions and changes as elements within the chang summary
+element.
+
+Change Summary Undo
+===================
+
+The undo method of a change summary is not implemented.
+
+Read-Only
+=========
+
+Read-only data elements are not supported by this implementation. Properties may be set read-only, but
+the property may still be modified without an error.
+
+Opposites
+=========
+
+Opposites are not supported by this implementation. 
+
+Date and Time
+=============
+Date support is limited to using a time_t. There are no calendar or duration style objects, and no
+helpers for conversions.
+
+
+BigDecimal and BigInteger
+=========================
+
+The equivalent of the java BigDecimal and BigInteger objects are not implmented.
+
+NLS support
+===========
+
+Data objects may contain multi-byte data in the form of an SDO string, but locale information is not
+stored with the data.
+
+The creation API only allows properties and types to have ascii names (taking a char* as the name).
+
+Inheritance
+===========
+
+Type inheritance is single only.
+
