//To make MgException a throwable PHP exception, we need to break its inheritance chain
//which means we have to ignore MgSerializable. Although this is part of the public API
//surface, it is nothing more than a "marker" base class for internal server/webtier
//plumbing, none of which concerns and MapGuide application built on top of this. This
//will affect the inheritance chain of other classes, but once again due to the "marker"
//nature of this class, the breakage of this inheritance chain is inconsequential.
%ignore MgSerializable;

//Now that the inheritance chain has been broken, we can re-base MgException on top of
//PHP exception
