I have a utility function that calls Xerces to do string transcoding. This
requires XMLPlatformUtils::Initialize() to be called. However, I can't
guarantee that a random client calling me has called this before. At the
same time, I can't just call it because the caller might be in the middle of
a parse.

How can I check if Xerces has been initialized already? I thought of
checking the value of the pointer that I need
(XMLPlatformUtils::fgTransService), but of course I won't be able to tell.
It will have a garbage value that looks just like a valid pointer.

Any help is appreciated.
