> DTDElementDecl.cpp && DTDElementDecl.hpp perform lazy evaluation on many
> of the get() methods.  This is used in cached grammars which may
> be shared by multiple threads and accessed unsynchonized.
> Lazy initialization is generally a bad pattern, but particularly in multithreaded
> applications.  It should be disabled for shared grammars.  
> I work around this by calling all the getters when I create my Grammar pool
> but I think this should not be necessary.
> It would be good if somebody could check all the lazy evaluations that might
> affect shared grammars.
