 <p>
-<code style="white-space: normal">BOOST_CLASS_EXPORT</code> would usually

-#include "my_class.hpp"  // which contains BOOST_CLASS_EXPORT(my_class)

-
-These headers can be in any order.  (In boost versions 1.34

-If no archive headers are included - no code should be instantiated. 
-This will permit <code style="white-space: normal">BOOST_CLASS_EXPORT</code> 
-to be a permanent part of the <code style="white-space: normal">my_class.hpp</code> .
-
+One approach would be to instantiate serialization code  for all archive classes included in the library.
+This would add to each executable a large amount of code that is most likely never called.
+Also it would needlessly slow down compilations of any program that uses the library.  Finally,
+the list of archives would be "built-in" to the library which would compilicate the addition of
+new or custom archive classes.
 <p>
-Note that the implementation of this functionality depends upon vendor
-specific extensions to the C++ language.  So, there is no guarenteed portability
-of programs which use this facility.  However, all C++ compilers which
-are tested with boost provide the required extensions.  The library
-includes the extra declarations required by each of these compilers.
-It's reasonable to expect that future C++ compilers will support
-these extensions or something equivalent.
+Another approach would be for the library user to somehow explicitly instantiate which archive classes 
+code should be instantiated for each class to be serialized. Users would have to include
+header files corresponding the archive classes to be instantiated.
+The list of instantiated archive classes would have to be manually kept in sync with the
+archive class headers actually included.  This was considered burdensome and error prone.
+<p>
+This implementation of <code style="white-space: normal">BOOST_CLASS_EXPORT</code> works in the 
+following way:
+<ul>
+  <li>All header modules of the form &lt;boost/archive/*archive.hpp&gt; are required to precede 
+  the header module <a href="../../../boost/serialization/export.hpp" target="export_hpp">export.hpp</a>.
+  <li>The header <a href="../../../boost/serialization/export.hpp" target="export_hpp">export.hpp</a>
+  builds a list of archive classes whose header modules have been previously included.  
+  It does this by checking to see which inclusion guard constants have been defined.
+  The header <a href="../../../boost/archive/detail/known_archive_types.hpp" target="known_archive_types_hpp">known_archive_types.hpp</a>
+  lists the archive header files which whose include guards will be checked.  If you create your own
+  archive class, you probably want to edit this file.
+  <li><code style="white-space: normal">BOOST_CLASS_EXPORT(my_class)</code> explicitly instantiates
+  serialization code for <code style="white-space: normal">my_class</code> for each archive in the list.
+</ul>
+Serialization code will be instantiated for a given archive class 
+if and only if the module that defines that archive class has been included in the program. 
+Given this, our program will contain all necessary code instantiations and no other.
+<p>
+For many styles of code organization this header sequencing requirement presents little problem. 
+ 
+Serialization code organized by class headers that are designed to be independent of archive
+implementations will look something like the following:
+<code><pre>
+// A.hpp
+// Note:to preserve independence from any particular archive implementation,
+// no headers from &lt;boost/archive/...&gt; are included.
+// Headers can be included in any order.
+#include &lt;boost/serialization/...&gt;
+#include &lt;boost/serialization/export.hpp&gt;
+... // include other headers that A depends upon
+
+class A {
+	...
+};
+
+BOOST_CLASS_EXPORT(A) // note: the export name of this class
+</pre></code>
+This style:
+<ul>
+  <li>permits the header to include all aspects of the serialization implementation.
+  <li>permits the header to be included anywhere else as part of some other class declaration.
+  <li>reflects the concept of headers as a "library of types" which
+  can be used independently in other programs or other parts of the same program.
+  <li>reflects a fundamental principle of the serialization library design in that the 
+  specification of serialization of any class is independent of any archive implementation.
+</ul>
+However, it might not always be possible or convenient to conform to the above style. Something
+like the following might be required or preferred:
+<code><pre>
+// A.hpp
+// headers can be included in any order
+#include &lt;boost/archive/text_oarchive.hpp&gt;
+#include &lt;boost/archive/text_iarchive.hpp&gt;
+...
+#include &lt;boost/serialization/...&gt;
+...
+// can't do the following because then A.hpp couldn't be included somewhere else
+// #include &lt;boost/serialization/export.hpp&gt;
+
+class A {
+	...
+};
+// can't do the following because export.hpp is not included !!
+//BOOST_CLASS_EXPORT(A) // note: the export name of this class
+</pre></code>
+As noted in the comments, this would work.  But 
+<code style="white-space: normal">#include &lt;.../export.hpp&gt;</code> can't be used
+without conflicting with other modules which use 
+<code style="white-space: normal">#include &lt;.../*archive.hpp&gt;</code>.  In this
+case we can move the export to an implementation file:
+<code><pre>
+// A.cpp
+#include "A.hpp"
+...
+// export.hpp header should be last;
+#include &lt;boost/serialization/export.hpp&gt;
+...
+BOOST_CLASS_EXPORT(A)

-<p>
-Well, not quite.
-<p>
-There are a couple of global data structures for holding
-information of serializable types.  These structures are
-used to dispatch to correct code to handle each pair
-of serializable types and archive types.  Since this
-information is shared among all archives, there is

-there SHOULD be no problem having mulitple archives
-open simultaneously - be it from the same or different

-<p>
-Well, almost.
-<p>
-With dynamically loaded code - DLLS or Shared Libraries, 
-these global data structures can be altered when a library
-is loaded or unloaded.  That is, in this case, these
-globa data structures can be altered after 
-<code style="white-space: normal">main(...)</code>
-is called.  So if a thread is dynamically loading/unloading
-modules which contain serialization code while an 
-archive is open there could be problems.  Also, if
-such loading/unloading is happening concurrently
-in different threads, there could also be problems.
-<p>
-It might not be easy to control this.  Is possible that
-some systems may not actually load modules until they
-are actually needed.  So even though we think that
-there is not dynamic loading/unloading of such code
